抄録

This paper describes a system for fast and accurate distance measurement based on the phase accordance method. This method uses two carries of different frequencies and detects the time reference points as the phase matching instances of the carries. The method was originally developed for ultrasound measurement systems, however, we applied it to a light distance measurement system and achieved better accuracy comparing with popular laser distance meters.
