According to the basic equation of pulsed range finder and the requirements for the precisions and distance, the specification of the semiconductor laser source is designed. There are digital circuits and analog circuits in the LD drive circuit.A narrow pulse width, high-current LD drive circuit is designed with the switching characteristics of the ZTX415. A semi-circular cross-section cylindrical lens group is used to collimate two directional semiconductor laser beams. The best optical system parameters are calculated. A relatively simple mechanical structure is designed and the result of the beam-shaping is good.
