20080316492 | Optical motion identification device utilizing partial total internal reflection light source and/or partial non-total internal reflection light source - An optical motion identification device utilizing partial total internal reflection light source and/or partial non-total internal reflection light source includes a light-emitting member, a code member and a light-sensing unit. The light-emitting member generates projecting light beams. The code member receives the projecting light beams generated by the light-emitting member at different angles and positions, and the code member has many total internal reflection surfaces in order to make the projecting light beams form many partial total internal reflection beams and a plurality of partial non-total internal reflection beams. The light-sensing unit disposes beside the code member for detecting the light intensity distribution of the partial total internal reflection beams and/or the partial non-total internal reflection beams projected on the light-sensing unit in order to determining a direction, a displacement, or a rotation angle of a movement of the code member relative to the light-emitting member or the light-sensing unit. | 12-25-2008 |
