LMS 기반 Multirate 적응 필터를 이용한 LDV자체진동 보상 기법

A In-housed Compensation Mechanism of Body Vibration In a Laser Doppler Vibrometer Based on Multirate LMS Filter

This paper presents an auxiliary beam-assisted adaptive compensation technique applied to alleviate the problem of LDV's body vibration. The LMS algorithm is applied to adaptively compensate the body vibration utilizing the reference signal provided by the auxiliary beam. The usefulness of the proposed technique is verified via computer simulations performed for diverse types of target signals and body vibration.
