Abstract
An optical encoder includes a coding element having a track with multiple transparent sections, a light source positioned to output light to the track, and a photodetector array, positioned to detect light that passes through the transparent sections of the track. The photodetectors of the photodetector array have larger width dimensions than the width dimensions of the transparent sections of the track. Resolution of the optical encoder may be adjusted by changing the resolution of the coding element.
