High resolution kilometric range optical telemetry in air by radio frequency phase measurement
2016
Review of Scientific Instruments
Preserved Fulltext
We have developed an optical Absolute Distance Meter (ADM) based on the measurement of the phase accumulated by a Radio Frequency (RF) wave during its propagation in the air by a laser beam. In this article, the ADM principle will be described and the main results presented. In particular, we will emphasize how the choice of an appropriate photodetector can significantly improve the telemeter performances by minimizing the amplitude to phase conversion. Our prototype, tested in the field, has
