Class Information
Number: 356/5.1
Name: Optics: measuring and testing > Range or remote distance finding > With photodetection > Of cw phase delay
Description: Subject matter that incorporates a continuous wave (CW) of modulated or unmodulated optical signal that is transmitted to and reflected from a target, such that the relative phase position of the returned wave is compared to the phase of the transmitted wave in order to determine the distance-proportional transit time to and from the target.
