Laser Based Data Signal Transmission Using Free Space Optics

Bhuvaneswari Balachander

Abstract :

The setup used is based on free space optical communication. In which communication between two PC’s is established using LASER light. IC MAX 232 is used. IR diodes are used for short distance communication between 2-3 m. This dis-tance could be further improved to up to hundred meters, by replacing IR LEDs with laser diodes. Laser pointers available commonly are used as the laser module in this setup which has about 3 mW power as output. Laser beam from one module is made to point towards the photodiode of the other module which is connected with the personal computer and vice-versa. Software module is writ-ten using C language to perform this process. This C codes are used in chatting and data transfer be-tween nodes only when Line of Sight must exists
