Abstract

A method of improving the accuracy of laser pulse range finding from ±10 m to ±1 m inexpensively by means of time scale-up is described. Time scale-up can stretch the entire flight time by a factor of 1000 and then the stretched result is counted to calculate the distance. The use of this technique decreases the resolution of counting from nanosecond to microsecond, therefore a separate counting oscillator followed by an interpolation operation is unnecessary. This technique can improve the accuracy of laser pulse range finding inexpensively and effectively.
