File Name: voice transmitter and receiver based on laser torch .zip
Embed Size px x x x x Using this circuit you can communicate with your neighbours 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 metres. The phototransistor of the receiver must be accurately oriented towards the laser beam from the torch.
Laser Audio Transmitter. This project is a proof-of-concept device that transmits an audio signal using a laser beam, while removing the need for the user to align the beam themselves. The receiver can be rotated within its horizontal plane, and uses a servo motor controlled by a microcontroller to automatically align it with the receiver. Light is already becoming a popular means of communication, thanks to fiber optics, which can guide optical data much like a wire transmits current. It might seem impractical, then, to use lasers without a guiding medium to transmit information. However, in contexts where a physical connection is impossible or unfeasible, and the need for a focused beam arises, it would seem logical to use laser light.
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. 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. 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. 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 And the total components with their specifications are elaborately explained in this paper. 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.

The hl is an easytouse tool that accurately measures elevations across the site, and is ideal for use with any rotating transmitter. Were trying to show wireless communication using an optical medium, which is why we wanted to use a laser transmitter and receiver.
