Combination-matching problems in the layout design of minilaser rangefinder

Beginning with an analysis of the practical laser rangefinder system, this paper deals with (1) the restrictive relations between each main structural parameter of the optical system, (2) the main problem in the layout design, and (3) how to obtain the optimal design scheme of the total performance of the instrument subject to given technology by partially reducing the refractive index of the optical splitting prism material.
