Heart Of Smart Workplaces 7 November Please reply me soon…. This not only receives the signal it also demodulates it. And lasers will sooner the ultimate replacement of radio signals.

Is there any specification for the condenser mic used…please reply soon.

The signal is them coupled through C8 to VR2. What should be the exact output of the circuit. My transmitter laser torch not glow what is the fault…? Right from the origin communication system had undergone several changes in terms of its advancement, continuous modernization taking place in every aspect of global communication.

Can we connect the output directly to the speaker without using the lm ic?? To avoid 50Hz hum noise in the speaker, keep the photo-transistor away from AC light sources such as bulbs.

Laser Based Transmitter & Receiver | Detailed Project Available

We use various types of lasers for transmission of audio signals some of them are Gas lasers, Chemical lasers, Excimer lasers, Fiber-hosted lasers, Photonic crystal lasers, Semiconductor lasers, Dye lasers, free electron lasers. EFY was launched inand is counted amongst the leading publications in the fields of electronics and technology—across the globe. Washbasin Mirror Light Controller. Pls reply…Can I use an audio jack instead of condenser mic in transmitter circuit.?


This circuit works perfectly with all the components as specified. But I wish to know more about its design and concepts.

The circuit works perfectly. Log into your account. To minimise the noise please follow the instructions given in the article.

And the total components with their specifications fuol elaborately explained in this paper. The reflected sunlight, however, does not coice any problem. The future scope for the laser based communication is to achieve the two way laser communication in spatial communications. 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.

The transmitter circuit Fig. IC2 amplifies the signal more and drives the speaker, LS1. All Time Fav Videos!

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 distances. Lasers exhibits high coherence and crystal clarity in terms transferring data. Depending Up their requirement different laser is used for different ranges.


I have made this circuit but all I can observe is a noise at the receiver speaker. A laser torch can transmit light up to a distance of about metres. Query is not clear.

Instead of RF signals, light from a laser torch is used as the carrier in a circuit. You have entered an incorrect email address! Electret condenser mic was used during the testing. Though it is youngest technology in communication it became the future scope for the scientists in spatial communication reeiver.

Yes, you may get some noise in the receiver. The overall advantages of our laser based voice transmitter and receiver is to provide speed and accuracy with high data rates, minimal interruptions and highly flexible.

Laser Based Transmitter And Receiver

The transistor puts out a signal that is proportional to the light from the LED. You should get the same audio signal at the output of the receiver side. Please enter your comment!

VR2 is a volume control for IC2. The measurement and analysis of process parameters such as temperature, flow, conductivity, speed, viscosity and stress play I am using a condenser mic.
