ABSTRACT



Laser as a communication medium can provide a good substitute for the present day communication systems as the problem of interference faced in case of electromagnetic waves is not there and high deal of secrecy is available. Use of laser in communication systems is the future because of the advantages of the full channel speeds, no communication licenses required at present , compa ....etc

LASER TORCH BASED VOICE TRANSMITTER AND RECEIVER
Using this circuit you can communicate with your neighbors wirelessly. Instead of RF signals, light from a laser torch is used as the carrier in the circuit. The laser torch can transmit light up to a distance of about 500 meters. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. The transmitter circuit (Fig. 1) comprises c ....etc

Dear sir/madam
We are the student of Lovely Professional University,Phagwara, Punjab , India

This is our last semester of B.Tech. and wehave to do capstone project.which is LASER based data transmitter and receiver.
We wants circuit diagram of laser based data transmitter and receiver using LASER light source and Microcontroller. The data at transmitter will be displayed on LCD at transmitter section . Then at receiver section using phototransister we will receive the digital data and that will be again displayed on LCD.
please also pr ....etc
