dc.description.abstractFree-space optical communication systems can provide high-speed, improved capacity, cost effectiveness, and ease of deployment for wireless networks. This paper addresses the design and construction of a laser transceiver. This laser transceiver can be used for data communications between two computers via free space optical link. In this project, the serial ports of the computers are used which are defined by JAVA. A laser pointer is used as the optical source for electrical to optical signal conversion at the transmitter section. Optoelectronic conversion is performed by a phototransistor at the receiver section. We use MAX 232 to convert RS 232 logic to TTL logic and then an optical transmitter circuit to transmit data via free space optical link. At the receiver we have an optical receiver circuit which receives data using a photo transistor and a MAX 232 again to convert TTL logic to RS 232 for the serial port at the receiving end computer. The desired baud rate can be set using the program. For transmitting data the program is executed once and whatever is present at the serial port is sent to the other computer via the free space optical link. At the receiver, the program is executed to receive data on the serial port. The laser transceiver allows any two computers with serial (RS-232) communication capability to communicate using a laser beam.en_US
