As for the technical college, practical education is required for lecture as well as practicum. This paperproposes the practical exercise that can be used in subjects such as Control and Digital signal processing. A newstudent experiment for distance measurement is proposed. First, it is described that the random modulationtechnique is useful for the students to understand concept of control. A laserdiode was used for the experiment.This technique is expected to have various applications. Secondly, an application example is shown. An RM-CW,random modulated continuous wave, LIDAR was optimized as for the range resolution, the power and the lengthof M sequence. Finally, it is demonstrated that the RM-CW LIDAR is useful to measure distance to buildings,hill, mountain, streets, and so on.
