Abstract
The paper compares various methods for constructing laser emitters in pulsed semiconductor rangefinders. Two semiconductor laser emitters with a wavelength of 905 nm, which are part of a pulsed range finder, are considered. The optical scheme of the transmitting and receiving channels of the range finder consists of an aspherical lens and an objective. The difference between laser emitters is the presence of a built-in cylindrical lens in one of them. The results of measuring the distance to the target by a rangefinder with both options for constructing emitters under various conditions are demonstrated.
