This paper investigates the optimal choice of the transmitted energy of a laser used in a transmissive vision distance meter. The relationship between the visible distance, the minimum blind area of the photoelectric conversion system, the emission energy of the laser and the distance between the instrument and the cooperation target is derived. The minimum detectable distance and the lower limit of the required laser emission energy are discussed respectively when the minimum dead zone of the photoelectric conversion system and the distance between the instrument and the cooperation target are determined. When the minimum detectable distance and the distance between the instrument and the cooperation target The relationship between the minimum dead zone of the photoelectric conversion system and the lower limit of the required laser emission energy is analyzed. The influence of the receiving aperture of the receiving lens on the lower limit of the required laser emission energy is analyzed. Some meaningful conclusions are obtained
