Abstract. A method is described, which makes it possible to increase efficiency of laser locator of optical devices. The approach employs temporally constant illumination to provide a high search rate at low detection range, and pulse-gated illumination to ensure high detection range at low search rate. Thus, the proposed method combines high search rate of constant illumination with relatively high detection range. Automatic range scanning in adjustable limits is introduced to improve the classical principle of pulse-gated illumination. Additional advantage is provided by redistribution of average power of laser emitter from short-range zone (where it is excessive) to long-range zone (where it is insufficient).
