I work on a project "distance meter kit " Here is the link. laser kit  There are videos. vide1 video2 In the comments under the video link to the file excel. This file is recorded measurement phase at a frequency of 45 MHz, 30 MHz, 3 MHz. Measurement of the phase increments of 100 millimeters. From the values of the phase, we can calculate the distance. 45 MHz Phase 0-360 = 3,75M. 30 MHz Phase 0-360 = 5M. 3 MHz Phase 0-360 = 50M I have a problem at the time of the transition phase from 0 to 360 or 360 to 0. It is not always properly defined range 0-3,75m or 3,75-7,5m Help calculate. thank.
