OPTICAL SPACE TRANSMISSION APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an inexpensive optical space transmission apparatus capable of carrying out stable communication by reducing an optical axis deviation correction error by an ununiform intensity distribution existing in a received light even when microscopic fluctuations take place in atmospheric air.

SOLUTION: The optical space transmission apparatuses are placed opposite to each other apart by a prescribed distance. Each optical space transmission apparatus carries out two-way information transmission / reception by using a transmission section that converts an electric signal into an optical signal and transmits the optical signal and by using a reception section that converts the received optical signal into an electric signal. An optical axis or a position detecting light receiving element in an optical system for the position detecting light receiving element that detects an incident direction of luminous flux transmitted from an opposed transmission section can be movable within a plane nearly perpendicular to the optical axis.
