  Abstract

An optical system that minimizes the loss of a laser beam in a LiDAR sensor that detects a distance and an object using a laser is most important. Therefore, in this paper, a high-efficient optical system was designed and verified by simulating the element technology of LiDAR sensor which can be applied to auto pilot of unmanned vessels. First, the collimation of the luminescent laser beam is the most important factor affecting the performance of the LiDAR sensor. Due to the characteristics of PLD(Pulse Laser Diode) using semiconductors, the light source itself is close to the point light source, and the collimation quality of the point light source is more advantageous than that of the refraction optical system. Secondly, we design and simulate the optical path that can enhance the beam collimation efficiency by applying the reflective optical system, and use a prism to correct the beam distortion.
