Abstract
A position detecting element that enables a position to be detected at high speed and high precision, and a range sensor using the same. The position detecting element is provided with a PIN photodiode array 1 having n segments and a parallel arithmetic processing portion 2 that calculates the segment having maximum intensity by comparing n outputs from the segments of the PIN photodiode array 1. The range sensor includes a light source by which the object to be measured is irradiated by optical beam, a lens that gathers rays of the reflected light from the surface of the object to be measured and the position detecting element mentioned above that detects the position of the light gathered by the lens.
