PROBLEM TO BE SOLVED: To provide an optical communication device capable of suppressing generation of a reception error of signal light even when a posture on reception side fluctuates against an arrival direction of the signal light.SOLUTION: An optical communication device 1 includes optical detectors 13A, 13B, a detection sensitivity correction part 21, a signal correction part 23 and a sensitivity control part 30. The sensitivity control part 30 sets a gain G of the detection sensitivity correction part 21 at 1, calculates a proportion k of an amplitude of an optical detection signal D1 to an amplitude of an amplitude optical detection signal D3 and sets the gain G of the detection sensitivity correction part 21 at the proportion k. The signal correction part 23 corrects the optical detection signal D1 using the amplitude optical detection signal D3 to output a reception signal during a reception period of signal light.SELECTED DRAWING: Figure 1 |
