Abstract
An optical device uses in a plane image input device. The optical device comprises a body including an incident end and an emergent end. After a light beam enters the body via the incident end, undergoes a total reflection, and emerges from the emergent end. Thus, the size of the plane image input device can be minimized and the optical energy attenuation can be reduced during the transmission process.
