ABSTRACT:
A computer input apparatus is disclosed which has improved safety control. The computer input apparatus includes a calibration circuit to control the operation current of a coherent light source to be above a minimum threshold required for normal operations, but below an upper threshold for safety reason. The computer input apparatus includes a fault detection circuit to monitor fault conditions. When this computer input apparatus employs a coherent light source, it does not require any optical lens to diminish optical power.
