ABSTRACT:
An optical output detector suitable for detecting the output of a laser diode for emitting light in a constant direction. The front emitted light generated from the laser diode as a light emitter is partially detected by a transmitting and diffracting unit, and the light intensity of the light emitter can be constantly maintained by detecting the light, thereby simplifying the manufacturing process and reducing the cost. Also, optical data can be stably processed by enhanced efficiency of the laser diode.
