Abstract
This paper presents the development of the Acquisition sensor which is a part of overall Acquisition, Tracking and Pointing (ATP) mechanism for maintaining the line of sight (LOS) between two Optical Communication Terminals (OCT). The ATP mechanism is basically used to align the transmitting and the receiving optical communication terminals which in turn can continuously transmit the data between them. The Acquisition sensor is designed to acquire the LASER image falling on it which is being transmitted by the transmitter terminal and to process this image to calculate the 2-axis angular error. This error is then used to re-position the terminal to maintain the LoS if it is out from the Field of View (FOV) of the transmitter by feeding this data to Tracking and Pointing modules of ATP mechanism.
