Abstract. In this paper we designed the circuit, using that circuit we can communicate with our neighbors wirelessly. Instead of RF signals, light from a laser torch. 5 Nov Using this laser based transmitter & receiver circuit you can Instead of RF signals, light from a laser torch is used as the carrier in a circuit. 16 Oct Download Project Report on Laser Torch-Based Voice Transmitter and Receiver. Right from the origin communication system had undergone.

Narrow beam divergence Laser transmitter and receiver units ensure easy, straightforward systems alignment and long-term stable, service free operation, especially in inaccessible environments, optical wireless systems offer ideal, economical alternative to expensive leased lines for buildings.

I am using a condenser mic. All Time Fav Videos!

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 answer about how we communicate with others by using laser technology.

This report involves the study transmitger wireless, open channel communication system using laser a carrier for voice signals.

Today there is major development going on Android OS and we have seen a major boom in Android ba Paper cone moves in accordance with electrical signal. Training Report on Residential Building Construction.


The future scope for the laser based communication is to achieve the two way laser communication in spatial communications. Compatibility with copper or fiber interfaces and no bridge or router requirements. Please reply me soon…. Automatically changes to Flash or non-Flash embed.

PopularPosts ul li img”. It can be used in conference halls. The transistor puts out a signal that rransmitter proportional to the light from the LED. Pls reply…Can I use an audio jack instead of condenser mic in transmitter circuit.?

Audio frequencies kaser from 20Hz to 20kHz but these frequencies are not heard in the same way I am using a laser torch and when it is pointed to the base terminal of the 2n photo transistor a sound can be heard.


Laser Based Transmitter And Receiver

There are no recurring line costs. Hope you will enjoy the FREE projects. In this paper, we study s You do not have the permission to view this presentation. Design Guides Pmods — How to get started? WordPress Embed Customize Embed. You should get the same audio signal at the output of the receiver side. Very-large-scale integration VLSI is the technology of creating an integrated circuit IC by blending billions of transistors Electret condenser mic was used during the testing. All the resources in this website are Laser torch based voice transmitter and receiver project report of charge.

Transmit the audio signal wirelessly using Laser torch. 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. To avoid 50Hz hum noise in the speaker, keep the photo-transistor away from AC light sources such as bulbs.

The circuit works perfectly. Hello, Welcome to Final Year Projects. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch. Top 10 Civil Engineering Projects for Students.
