The Difference

The phase method of laser ranging modulates laser by using a continuous wave, calculating the time interval indirectly through the phase variation of the modulation wave when it propagates between the measured targets, and make out the measured distance. This paper uses the principle of phase method of laser ranging, proposes the overall design scheme of phase method of laser measurement system which achieves the distance measurement by using methods of the difference frequency measurement and digital phase discrimination as well as the microcontroller. It also analysis the system possible errors from many aspects, puts forward the appropriate measures to improve the accuracy of the measurement.
