WebThe distance-of-flight measurement is based on the continuous wave laser ranging principle. Interference occurs when two light beams have the same frequency, and the phase difference is a constant . During constructive interference, the two beams are in phase and the peaks of both beams reinforce each other, resulting in a bright fringe ... WebThe important thing to interfere is that the two beam are coherent, that means that the differences in wavelength between the two beam is constant in time and do not vary.
