적외선 펄스 레이저를 이용한 전방차량과의 거리 계측

This study, is the basic research on the development of measuring system for the distance to the forward vehicle from the following one. In the methodology, the optical pulse method is applied, and the transit time of the pulse is detected by using high resolution counter to estimate the distance. As a optical source, a infra-red pulsed laser was used, and the concrete optical system was constructed. The performance of the measurement system was proved by basic experiments and by comparing with the theoretical predictions based on the diffraction model and the simple diffusion model.
