摘要： A photodetector has a photo-receiving portion for receiving a return beam consisting of a main beam, a leading sub beam, and a trailing sub beam to produce photo-received signals and a processing circuit for processing the photo-received signals to produce main and sub processed signals. The photo-receiving portion includes a group of leading sub photo-receiving elements for receiving the leading sub beam to produce leading sub photo-received signals and a group of trailing sub photo-receiving elements for receiving the trailing sub beam to produce trailing sub photo-received signals. The processing circuit is configured to produce, in a normal mode, as the sub processed signals, added signals obtained by adding the leading sub photo-received signals and the trailing sub photo-receiving signals and to produce, in a test mode, as the sub processed signals, signals obtained by processing only the leading photo-received signals.

摘要： In order to fix a laser diode 12 to an optical base 11, a plurality of threaded pins 15 are at first fixed to the optical base by the use of, for example, an anaerobic adhesive. Then, the laser diode is faced to the optical base in an area between the threaded pins. The laser diode is adjusted in position and angle with respect to the optical base by, for example, 5 axes 3D adjustment. Thereafter, the laser diode is fixed to the threaded pins by the use of solder pieces 16.
