Abstract
An assembly for optoelectronically sensing position includes a light source, a coded element, and a plurality of photosensors. Holes are disposed in the coded element to define a plurality of digital codes. The light passes through the holes in the coded element to illuminate the photosensors. The holes are sized and the photosensors are positioned such that the light is transmitted to more than one of the photosensors through each of the holes.
