In the conventional thermograph systems, expensive infrared lens systems are usually used for accomodating infrared beams to high speed optical scanners. In this study, a cheap focussing mirror with a two dimensional scanner are used for the development of medical infrared thermograph system in which high speed imaging is not critically required. The infrared thermograph system can be used for two dimensional imaging of human skin temperature by measuring the amount of infrared lights radiating from it. It has been experimentally proven that the accuracy of temperature measurements using the developed system is under 0.1$^{\circ}C$ with image matrix size of 256${\times}$240, and imaging time of 4 seconds.

Recently, while 3D sports game increases, the research that it recognizes the operation of the real user actively progresses. Most of all, the research about the golf is active. In this paper, the image acquiring in a high-speed CCD camera measures the flight data of the golf ball through the image processing. While photographing, the high-speed camera, using this system, exposes an image at regular intervals. And line scan camera checks whether the golf ball passed or not. After the location information of the calculated golf ball calculates a speed and a direction by using the physical formula, it applies the golf simulation.

In order to measure the retina thickness, the retina photographing system and the multi-channel high speed image data acquisition system is developed. This system requires the optical processing techniques and the high speed image processing techniques. The HeNe laser beam is projected the retina in artificial eye and then we sensed the reflected laser signal using APD array. The laser projection system on retina using optical instruments is implemented. In order to project the plane laser beam on retina, laser photographing system used the polygon mirror for horizontal scanning and the galvano mirror for vertical scanning. We acquired retina images in each channel of APD array, transferred computer using PCI interface the image data after real-time A/D converting.

In order to measure the retina thickness, there are to need the 3-D retina photographing and the high speed signal processing system. In this paper, we introduced the retina photographing system and the 16-channel high speed image data acquisition system. There are able to measure the retina thickness with sensing image the returned laser signal to APD sensor after there were projected the HeNe laser on retina. We developed the laser projection system to sense a reflected image of the retina using APD sensor, the 16-channel high speed A/D converter and PCI master interface card for image transmission into computer.

By utilizing OSMI (Ocean Scanning Multi-spectral Imager) onboard KOMPSAT-1, the moon can be imaged. Because the moon has no atmosphere and reflects sun lights at a constant rate, it can be the radiance source for calibration of OSMI. But there are a lot of risks which made KOMPSAT-1 enter into safe-hold mode. So planning the imaging of the moon with OSMI should be determined seriously with consideration to information on KOMPSAT-1 operation, the moon, the sun, etc. But it takes a long time for determining the imaging time of the moon using MCE(Mission Control Element) simulator and there are operational problems to be solved. In this paper, fast simulator for determining imaging time for the moon with OSMI has been developed. The proper timeline for imaging the moon and the position of the moon image in OSMI image coordinates and the phase of the moon are determined. STK was used for acquiring information on KOMPSAT-1, the moon, the sun and the characteristitcs of OSMI are considered. As a result, we can determine imaging time of the moon with OSMI much faster and efficiently.
