This work is concerned with wireless optical receiver .The normal point to point wireless optical communication (WOC) systems with a static receiver will be modified into an auto adjustable/self alignment receiver. The newly invented optical antenna has provoked the inspiration of designing an optical antenna/receiver which is able to self align itself to get the transmitted signal from the transmitters located in different buildings with each building varying in height and angle from the receiver building. The source code details of the PIC microcontroller will be articulated clearly for further enhancements of the system. The primary advantages of this system is that, this system increases total detection optical power and simultaneously improves the signal to noise ratio (SNR) of the WOC link due to the usage of the optical antenna. The high cost of maintaining and reconfiguring wired communication has resulted in the active usage of wireless communication system. Wireless communication system can be divided in two main categories which is the radio frequency (RF) or Infrared (IR) type. The IR type is increasingly famous because of its low cost and free licensing.
