<P>PROBLEM TO BE SOLVED: To provide a photodetector and an optical communication system which have a simple and compact configuration to be able to carry out light detection corresponding to a change in incident light in an incident direction. <P>SOLUTION: The photodetector 1 comprises an incident window 2 receiving incident light, an optical deflector 3 which deflects light incident on the incident window 2, a condensing means 4 which condenses light deflected by the optical deflector 3, and a light-receiving means 5 which detects light condensed by the condensing means 4. <P>COPYRIGHT: (C)2007,JPO&INPIT |
