Reflective Optical Encoder Capitalizing on an Index Grating Imbedded in a Compact Smart Frame

A reflective optical encoder has been proposed and realized capitalizing on a miniaturized sensing head, which integrates both a pair of index gratings and a beam router in a plastic smart frame. The index gratings play a role in selectively transmitting the incident beam carrying the periodic grati...
