<P>PROBLEM TO BE SOLVED: To provide an optical space communication apparatus a light receiving element of which can receive an incident light with a greater level (can improve the dynamic range). <P>SOLUTION: The optical space communication apparatus for carrying out communication between points apart from each other controls a direction angle in response to a reception level signal in order to enhance the dynamic range of the light receiving element at an excess input. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
