ABSTRACT:
An integrated transmitter/receiver system which uses a hybrid component for both the light source and the light detector, with holographic optical elements for dividing the light beam into two or more beams. The hybrid component contains a laser diode and a detector mounted on the same mechanical structure. This invention allows the placement of all the components substantially along a single optical axis. This arrangement reduces alignment problems and vibrational errors.
