Our project ma goal is to provide a better option where large data is to be transferred with in a shorter duration of time along specified recwiver. But I wish to know more about its design and concepts. Hi do you have the circuit diagram of laser communication transmitter and wireless laser communication receiver. Friday, November 9, If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver.

Project Report on Laser Torch-Based Voice Transmitter and Receiver | Projects

And lasers will sooner the ultimate replacement of radio signals. Is there any specification for the condenser mic used…please reply soon. Since from the very beginning of global communication through radio frequency waves to fiber optic communication the entire criteria had taken several modifications, recently by introduction of lasers in communication systems had made revolutionary change in field of spatial communication in fact I will the future for groundbreaking developments going to take place in communication systems.

To avoid 50Hz hum noise in the speaker, keep the photo-transistor away from AC light sources such as bulbs.


The gain of the op-amp can be controlled with the help of 1-mega-ohm potmeter VR1. Torcg into your account. My transmitter laser torch not glow what is the fault…?

Laser Torch Based Voice Transmitter and Receiver Block Diagram | Projects

IC2 amplifies the signal more vased drives the speaker, LS1. Query is not clear. Pls reply…Can I use an audio jack instead of condenser mic in transmitter circuit.?

I have made this circuit but all I can observe is a noise at the receiver speaker. Shannon Fano Elias encoding algorithm is a precursor to arithmetic coding in which probabilities are used to Please enter your name here.

Washbasin Mirror Light Controller. Transmit the audio signal wirelessly using Laser torch.

However, the 3-volt laser torch after removal of its battery can be directly connected to the circuit—with the body of the torch connected to the emitter of BD and the spring-loaded lead protruding from inside the torch to circuit ground.

The overall advantages of our laser based voice transmitter and receiver is to provide speed and accuracy with high data rates, minimal interruptions teport highly flexible. VR2 is a volume control for IC2. Laseer audio signal into transmitter side. Though it is youngest technology in communication it became the future scope for the scientists in spatial communication advancements.

Laser Based Transmitter And Receiver

I am using a laser torch and xnd it is pointed to the base terminal of the 2n photo transistor a sound can be heard. Please enter your comment! The proposed circuit basically had the transmitter circuit and this block consists of transistor amplifier BC coupled with condenser microphone, and an audio modulator BD But the sensor should not directly face the sun.


Rceiver Time Fav Videos! Other than this I am not even sure whether the mic is peaking up the sound or the transmission is happening or the receiver is working properly.

Raspberry Pi is a low-cost, high-performance, credit-card-sized computer for learning, solving problems and having fun. The performance characteristics and the practical results verified with real time applications. EFY was launched inand is counted amongst the leading publications in the fields of electronics and technology—across the globe.

The circuit works perfectly. In this paper we implemented Laser torch-based voice Transmitter and receiver technology for exchanging data between stations, this paper addresses a new means of voice transfer between persons. A laser tlrch can transmit light up to a distance of about metres.

Depending Up their requirement different laser snd used for different ranges. Useful Raspberry Pi Projects. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch.

Lasers exhibits high coherence and crystal clarity in terms transferring data. Yes, you may get some noise in the receiver. The main operation of our project is based on the two sections one is laser transmitter section and the other laser receiver section the combination of these two sections constitutes the entire circuit block.
