【 摘 要 】

A method for improving the accuracy rangefinder with a semiconductor laser operating in the mode of accumulation of weak reflected signals at multiple sensing target, is described. It is shown that the use of in receiving channel of rangefinder two threshold electric drive with automatic adjustment of levels, can improve the signal/noise ratio and improve the accuracy of measurements. The results of laboratory and field tests distance measuring channel observation device are given.
