Patent ID: 7554076

Claim:
An optical sensor system for detecting a moving object, comprising: a first optical transceiver module, comprising: a first optical transmitter that produces at least one beam of light, the first optical transmitter further comprises a first aspherical lens that collimates a beam of light from a first laser diode and a first diffractive grating that splits the collimated beam of light from the first aspherical lens into a first plurality of beams of light; a first optical receiver that is operative to detect reflected light from the first optical transmitter, the first optical receiver comprises a first collector lens that directs reflected light associated with the first plurality of beams to respective detectors of a first set of detectors; a first housing for housing the first optical transmitter and the first optical receiver; and a second optical transceiver module, comprising: a second optical transmitter that produces at least one beam of light, the second optical transmitter further comprises a second aspherical lens that collimates a beam of light from a second laser diode and a second diffractive grating that splits the collimated beam of light from the second aspherical lens into a second plurality of beams of light; a second optical receiver that is operative to detect reflected light from the second optical transmitter, the second optical receiver comprises a second collector lens that directs reflected light associated with the second plurality of beams to respective detectors of a second set of detectors; and a second housing for housing the second optical transmitter and the second optical receiver.
