ABSTRACT:
The method comprises inserting an optical detector into a movable holder, illuminating the optical detector by a source of optical energy to cause the detector to generate an output representative of intensity of illumination incident on the detector, moving a selected one of the source and holder to a position in which the output of the detector corresponds to maximum intensity of illumination, maintaining the moved one of the source and holder in said position and replacing the optical detector by a fiber optic to be aligned. The apparatus comprises a holder, a light source, and optical detector removably mounted in the holder for illumination by the light source, a circuit connected to output of the optical detector for determining when the output of the optical detector corresponds to maximum intensity of illumination, and means for moving a selected one of the holder and light source to a position in which the output of the detector corresponds to maximum intensity of illumination.
