ABSTRACT:
An apertured reflection plate obliquely oriented with respect to a fiber optical axis allows light to be introduced through the aperture to a condenser lens for introduction to the fiber. Light reflected from the exit face of the fiber will come out of the entrance end face, be spread by the lens and be reflected by the outer regions of the reflection plate to a light detecting element. In response to an abnormal detection signal, the laser can be disabled.
