Abstract
An optical encoder and optical encoding system are disclosed. Specifically, an encoder having a light detector elevated relative to a light source is described. The relative height difference between the light source and the light detector enables the optical encoder to minimize noise at the light detector without requiring a separate light baffle between the light source and light detector. Methods of manufacturing and operating such an encoder are also described.
