The transmitter uses 9V power supply. I have made this circuit but all I can observe is a noise at the receiver speaker. To avoid 50Hz hum noise in the speaker, keep the photo-transistor away from AC light sources such as bulbs.

Laser Based Transmitter And Receiver

C5 couples this audio to T4 and T5 which amplify the signal. This electronic media starting from satellite communications had invented new dimensions in the field of wireless communication, research in these areas created a new concept of communication by means of lasers, no one ever expected this kind of development in communication strategies and its always a raising question that how we communicate by implementing lasers, in our project we give a detailed transmitte about how we communicate with others by using laser technology.

The transistor puts out a signal that is proportional to the light from the LED. A laser torch can transmit light up to a distance of about metres. 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. But the sensor should not directly face the sun. 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.


Transmotter do you have the circuit diagram of laser communication transmitter and wireless laser communication receiver. Our project ma goal is to provide a better option where large data is to be transferred with in a shorter duration of time yransmitter specified distances.

The measurement and analysis of process parameters such as temperature, flow, conductivity, speed, viscosity and stress play This circuit works perfectly with all the components as specified. The reflected sunlight, however, does not cause any problem. The signal is them coupled through C8 to VR2. Query is not clear. Is there any specification for the condenser mic used…please reply soon.

Lasers voie high functional abilities and ideal choice for less interference transmission had found many applications in recent days. Electret condenser mic was used during the testing. Log into your account. But I wish to know more about its design and concepts. Can we connect the output directly to the speaker without using the lm ic??

Shannon Fano Elias encoding algorithm is a precursor to arithmetic coding in which probabilities are used to 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.

The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. T3 is a photo sensitive transistor which receives the laser from the LED transmitter.

If there is any obstruction in the path of the laser beam, no sound will be heard from the receiver. Please reply me soon…. Please enter your name here.

Pls reply…Can I use an audio jack instead of condenser mic in transmitter circuit.? To minimise the noise please follow the instructions given in the article. Friday, November 9, 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.


All Time Fav Videos! 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. This not only receives the signal it also demodulates it. Transmit the audio signal wirelessly using Laser torch. IC2 amplifies the signal more and drives the speaker, LS1. EFY was launched inand is counted amongst the leading publications in the trahsmitter of electronics and technology—across the globe.

Useful Raspberry Pi Projects.

Laser Based Transmitter & Receiver | Detailed Project Available

The performance characteristics and the practical results verified with real time applications. Please enter your comment! 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. Rdceiver of RF signals, light from a laser torch is used as the carrier in a circuit. Depending Up their requirement different laser is used for different ranges.

What should be the exact output of the circuit. The mic is the audio input. 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.

You have entered an incorrect email address! Other than this I am not even sure whether the mic is peaking up the sound or transjitter transmission is happening or the receiver is working properly. The transmitter circuit Fig.
