<P>PROBLEM TO BE SOLVED: To realize an optical space communication device which is low in cost, small in size and light in weight, and can correct the deviation of an optical axis at high speed. <P>SOLUTION: An optical system is separated to a collimate optical system and a separation optical system 11, which is movable independently from the collimate optical system. Peripheral circuits of a light emitting element such as LD and a light receiving element such as an APD are placed at a different place, and connected with the separation optical system through an optical fiber or a minimum cord or cable to drive the separation optical system at high speed with small force. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
