Abstract

This paper deals with a fast rangefinder based on laser scanning space-encoding method. In the first place the principle of image-encoding is introduced and the calculation formulas of measurement values in 3D rectangular coordinate system are given. In the second place the design rules are put forward at the angle of the measuring volume, shading light and received light power properties. At last the measurement errors caused by quantization errors, the resolutions and their errors are discussed through error analysis, and then the design rules to reduce effect of quantization errors are presented.
