Abstract(summary):

The purpose of this paper is the comparison of two phase measurement methods commonly used in precision rangefinder systems and their suitability to work with high frequency signals. Basic detection circuits for an FFT and an IQ-based methods were proposed and hardware limitations were considered. A set of simulations to assess the behavior of the algorithms in the presence of the noise was performed. An influence of the ADC resolution on the measurement accuracy was also assessed. It is proved that the IQ-based method shows better resilience to signal distortions and puts lower requirements on the ADC circuit thus is better suited for real time high resolution laser rangefinders.
