Paper Abstract

In the pulse coded LIDAR system, the number of laser pulses used at a given measurement point changes depending on the optical modulation and the method of spreading code used in OCDMA. The number of laser pulses determines the pulse width, power, and duration of the pulse transmission of a measurement point. These parameters determine the maximum measurement distance of the laser and the number of measurement points that can be employed per second. In this paper, we suggest possible combinations of modulation and spreading technology, evaluate the performance and characteristics of them, and study optimal combinations according to varying operating environments.
