General aviation and air transport are two wings of the civil aviation industry. Chinese air transport is developing rapidly, and has become the world second air transport system only second to US since 2005. However, Chinese civil aviation is far behind the world average level, and cannot meet requirements of economic construction and social development. The transition and structural adjustment of Chinese economy provide the general aviation with a unprecedented broad market. The prospect of general aviation is promising and anticipated. The development of general aviation industry needs the legislative supports, and the current legislative conditions of Chinese general aviation are undoubtedly far behind the realistic requirements. Accelerating the legislation in Chinese general aviation industry requires scientific legislation concept. First, Legislation must promote development of general aviation industry. The general aviation will serves as a Chinese emerging industry that boosts domestic demand, promotes employment and expedite domestic economic development. We should, based on both the concept of promoting the industrial development of general aviation and national industrial planning, enact and rectify relative laws and regulations. And we should also straighten out the relationship between aviation security and industrial development and promote the revolution of low-altitude airspace management in an all-round way, in order to improve the utilization rate of airspace resources, classify and establish airspace, simplify examination and approval procedure and intensify operation management. In addition, what we should do is to expedite the infrastructure layout construction, guide the differentiated but coordinated development of general aviation industries in various areas, establish a united supervision mechanism of general aviation, redistrict the responsibilities of Chinese Air Control Agency and set up legislation, law enforcement and judicial systems with clarified institutions, clear positioning and classified responsibilities, so as to usher in a new era of the legislative management of Chinese general aviation industry. Second, shift the focus from regulations to both regulations and services. Considering the particularity of the general aviation, we should use American practices for reference and take into account both regulation and service functions when enacting general aviation laws. For example, we should reduce administrative licensing and market supervision, and adopt "criteria" and "approval" management systems for non-commercial and commercial aviation. Furthermore, pay attention to social benefits. Complete social rescuing mechanism through legislation. It should be clarified in legislation that general aviation operators should take the responsibilities of, and ensure to realize social benefits of environmental protection and ecological balance .Finally, rise in line with international standards. Modify Chinese regulations which is inconsistent with international ones to remove barriers to international cooperation. Specify basic legislative principles. One is the principle of coordination. Realize coordination between the civil aviation and general aviation, between military aviation and civil aviation, and among departments. Two is the principle of pertinence. The general aviation has its own rules and specialties, needing to be standardized using specialized laws and regulations. Three is the principle of efficiency. To realize time and space values of general aviation, we should complete rules in aerospace openness, general aviation airport construction, general aviation operations, and regulation enforcement. Four is the principle of security. Balance the maximum use of resources of Chinese airspace and the according potential threats to Chinese national interests and social security, and establish a complete insurance system which functions as security defense and indemnificatory measure. Establish a unified legal system. Currently, the system of Chinese general aviation laws consists of national legislation, administrative laws and regulations and civil aviation regulations (CAR). Some problems exist in three components of the system, including too general content, unclear guarantee measures, incomplete implementation details, and lacking corresponding pertinence and flexibility required by general aviation regulations, stringency of operation management and standards, and uniformity of standards. A law and regulation system, centered on laws and consisting of administrative laws regulations, industrial regulations, implementation details, industrial policies and local laws and regulations, should be established. It is suggested to modify the Civil Aviation Law to make general aviation laws complete, enact the Regulations of General Aviation Development, and accelerate the establishment, modification and abolition of Chinese general aviation laws to intensify the coordination and uniformity of regulations.

광학측정기법 중 주파수 스캐닝 간섭계는 기존 3차원 측정기법과 비교하여 광학 하드웨어 구조가 측정과정동안 고정되어 있어, 대물렌즈나 대상물체의 수직 스캐닝 없이 단지 광원의 주파수만 특정한 주파수 밴드내에서 스캐닝 하여 대상물체에 주사되므로, 우수한 광학 측정 성능을 보인다. 광원의 주파수를 변경하여 간섭계를 통해 간섭 영상을 획득한 후, 밝기 영상 데이터를 주파수 영역 데이터로 변환하고, 고속 푸리에 변환을 통한 주파수 분석을 이용하여 대상 물체의 높이 정보를 계측한다. 하지만, 대상물체의 광학적 특성에 기인한 광학노이즈와 주파수 스캐닝동안 획득되는 영상의 수에 따라 증가하는 영상처리시간은 여전히 주파수 스캐닝 간섭계의 문제이다. 이를 위해, 1) 편광기반 주파수 스캐닝 간섭계가 광학 노이즈에 대한 강인성을 확보하기 위해 제안되어진다. 시스템은 주파수 변조 레이저, 참조 거울 앞단의 ${\lambda}/4$ 판, 대상 물체 앞단의 ${\lambda}/4$ 판, 편광 광분배기, 이미지 센서 앞단의 편광기, 광섬유 광원 앞단의 편광기, 편광 광분배기와 광원의 편광기 사이에 위치하는 ${\lambda}/2$ 판으로 구성된다. 제안된 시스템을 이용하여, 편광을 기반으로한 간섭이미지의 대조대비를 조절할 수 있다. 2) 신호처리 고속화 방법이 간섭계 시스템을 위해 제안되며, 이는 그래픽 처리 유닛(GPU)과 같은 병렬처리 하드웨어와 계산 통합 기기 구조(CUDA)와 같은 프로그래밍 언어로 구현된다. 제안된 방법을 통해 신호처리 시간은 실시간 처리가 가능한 작업시간을 얻을 수 있었다. 최종적으로 다양한 실험을 통해 제안된 시스템을 정확도와 신호처리 시간의 관점으로 평가하였고, 실험결과를 통해 제안한 시스템이 광학측정기법의 실적용을 위해 효율적임을 보였다.

As the Reublic of Korea revised the Commercial Code including 40 articles of air transport enacted newly on May 23, 2011, so Korea became first legislative examples in the Commercial Code of the developed and developing countries. I would like to explain briefly the main contents of my paper such as (1) history of enacting newly Part VI (air transport) in the Korea's revised commercial law, (2) legal background enacting newly Part VI (air transport) in the Korea's revised commercial law and the problems on the conditions of air transport, (3) every countries' legislative examples on the civil liability of aircraft's operator, (4) unlawful Interference Convention and general risk convention of 2009, (5) main contents and prospects of the revised Commercial Code for the liability of aircraft's operator etc as the followings. Meanwhile as the Aviation Act, Commercial Code and Civil Code in Korea and Japan did not regulated at all the legal basis of solution on the disputes between victims and offender for the amount of compensation for damage due to personal or property damage caused by aircraft accidents in Korea and Japan, so it has been raised many legal problems such as protection of victims, standard of decision in trial in the event of aircraft accident's lawsuit case. But the Korean Revised Commercial Code including Part VI, air transport regulations was passed by the majority resolution of the Korean National Assembly on April 29, 2011 and then the South Korean government proclaimed it on May 23 same year. The Revised Commercial Code enforced into tothe territory of the South Korea from November 24, 2011 after six month of the proclaimed date by the Korean Government. Thus, though Korean Commercial Code regulated concretely and respectively the legal relations on the liability of compensation for damage in the contract of transport by land in it's Part II (commercial activities) and in the contract of transport by sea in its Part V (marine commerce), but the Amended Commercial Act regulated newly 40 articles in it's Part VI (air transport) relating to the air carrier's contract liability on the compensation for damage caused by aircraft accidents in the air passengers and goods transport and aircraft operator's tort liability on compensation for damage caused by the sudden falling or collision of aircraft to third parties on the surface and so it was equipped with reasonable and unified system among the transport by land, marine and air. The ICAO adopted two new air law conventions setting out international compensation and liability rules for damage caused by aircraft to third parties at a diplomatic conference hosted by it from April 20 to May 2, 2009. The fight against the effects of terrorism and the improvement of the status of victims in the event of damage to third parties that may result either from acts of unlawful interference involving aircraft or caused by ordinary operation of aircraft, forms the cornerstone of the two conventions. One legal instrument adopted by the Conference is "the Convention on Compensation for Damage to Third Parties, Resulting from Acts of Unlawful Interference Involving Aircraft" (Unlawful Interference Convention). The other instrument, "the Convention on Compensation for Damage Caused by Aircraft to Third Parties" (General Risk Convention), modernizes the current legal framework provided for under the 1952 Rome Convention and related Protocol of 1978. It is desirable for us to ratify quickly the abovementioned two conventions such as Unlawful Interference Convention and General Risk Convention in order to settle reasonably and justly as well as the protection of the South Korean peoples.
