The amplitude map shows each pixel’s return amplitude in a 12-bit value (0–4095). The amplitude map can be treated as a grayscale image, and processed using popular image processing algorithms, such as blob and edge detection. In general, the higher the amplitude, the more accurate a pixel’s phase measurement; therefore, the amplitude map is also called confidence map by some, and it can be used to weigh successive phase measurements in an average filter.
