Abstract

Based on active free space optics, we designed a binocular device with independent receiver and transmitter using positioning photodiode, quadrant photodiode, and voice coil motor. We proposed the alignment method using five photodiodes for the method of beam alignment. The estimation error of alignment was 30.1 mm. Basic communication experiments were conducted using two binocular devices. It is proved that free space optics communication can be performed by the designed active free space optics device.
