Answer   There are basically two configurations of lidars-monostatic and bistatic monostatic is one in which the transmitter(LASER) and the receiver(telescope) h…ave the SAME axis ,collinear configuration In bistatic lidar they dont have the same axis.you can imagine the laser and the receiver separated by 50-100mts both are aligned at angles whereas monostatic models have the laser and the receiver very close by both of them have advantages and disadvantages that you can figure out logically (MORE)

The only difference is laser light used in lidar instead of radio waves in radar that means in radar they are using radio waves but in lidar we are using laser light by means …of near infrared, green laser like that we are using many laser pulse in lidar technology (MORE)
