My name is Devika Vishwanath. I am in grade ten at Seaquam Secondary in Delta, BC. This year it is my third time participating in the CWSF. I find Math and Science extremely interesting and I especially love Physics. My other loves are music and dance. I play the piano and the flute, which gave me opportunities to play in my school band and in my community orchestra. I was the music award winner in my elementary school as well. I have been learning Indian classical dance for ten years now and I do stage performances. My other interests include hiking and reading. I have also been in student council and continuously volunteer for the community. The secret of doing a great science project is blending your crazy ideas with systematic methods. Do not just solve your problems; solve them in ways that have never been tried before.

Free-Space Laser Communication
Region:South Fraser
City:Delta, BC
School:Seaquam Secondary
Abstract:Free-space laser communication uses lasers to transmit data without the use of media, such as fibre optic cables. This project experimented on finding an optimum design for a free-space laser communication system. Analog signals were superimposed on a carrier laser beam using amplitude modulation. The beam was transmitted through free-space and demodulated at the receiving end. Minimum signal distortion was the prime consideration.
