Auto tracking for mobile FSO system in line of sight by measuring the captured power

Fso is a FSO is a line-of-sight technology that uses invisible beams of light to provide optical bandwidth connections. Today, FSO technology has enabled the development of a new category of outdoor wireless products that can transmit voice, data, and video at bandwidths up to ۱.۲۵ Gbps. This optical connectivity doesn't require expensive fiber-optic cable or securing spectrum licenses for radio frequency (RF) solutions. FSO technology requires light. The use of light is a simple concept similar to optical transmissions using fiber-optic cables; the only difference is the medium. Light travels through air faster than it does through glass, so it is fair to classify FSO technology as optical communications at the speed of light. Now there is a constraint to this technology. It should be fixed in both side of transmitter and receiver .Here is described the effect of incident optical size upon the quadrant photodetector on the displacement detection while varying the receiver or transmitter. It is showed that can be possible, communication with mobile FSO.Then one of the receivers by full duplex line of sight to the other is moving far and near .This will be implemented by using PSDs.
