3.3.5 Phase

The phase map is a measurement of each pixel’s relative phase between the emitted light and the reflected light. The phase is nearly proportionally with the actual distance. The difference between raw phase and processed phase is the phase offset. The phase offset may be different for each pixel, and may be a function of temperature and received amplitude. Correcting for the phase offset is the main focus of the calibration process.
