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.

Who doesn't love lasers? More powerful lasers may cause blindness instantly. If working with a powerful laser, I strongly recommend making a laser lab, and using laser goggles for the frequency of your laser. A communication system pretty much always breaks down to two parts, a transmitter and a receiver. So really it's two circuits. For this project I am going to keep both of them very basic. So let's start with the parts list.

Spread-spectrum techniques in optical communication using transform domain processing Abstract: A method of applying spread-spectrum techniques to optical communication is presented. The interference-suppression capability of spread-spectrum systems is shown to be enhanced by optical transform domain processing, and a design for spectral coding at optical frequencies is given. The encoding system is based on optical pulse compression and shaping. Several possible implementations of this system are suggested, and applications to fiber optics, laser radar, free-space optical communications, and other systems are discussed.

This laser communication system transmits sound or music signals through a laser beam. The intensity of the laser beam changes with the amplitude of the sound signal. The voltage variation on the solar panel is amplified by a low-voltage audio power amplifier LM and reproduced by a speaker. The maximum output of audio amplifier LM is 1 watt, while its voltage gain is 20 to The circuit consists of a transmitter and a receiver.

Free-Space Laser Communications pp Cite as. Free-space laser communication systems have the potential to provide flexible, high-speed connectivity suitable for long-haul intersatellite and deep-space links. For these applications, power-efficient transmitter and receiver designs are essential for cost-effective implementation. While spectral efficiency has long been a key design parameter in the telecommunications industry, the many THz of excess channel bandwidth in the optical regime can be used to improve receiver sensitivities where photon efficiency is a design driver. Furthermore, the combination of excess bandwidth and average-power-limited optical transmitters has led to a new paradigm in transmitter and receiver design that can extend optimized performance of a single receiver to accommodate multiple data rates.

Free-space optical communication FSO is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. This contrasts with using solids such as optical fiber cable. The technology is useful where the physical connections are impractical due to high costs or other considerations. Optical communications , in various forms, have been used for thousands of years.

Introduction

 - Внезапно Беккер понял, что говорит чересчур громко. Люди на соседних койках приподнялись и внимательно наблюдали за происходящим. В дальнем конце палаты появилась медсестра и быстро направилась к. - Хоть что-нибудь, - настаивал Беккер. - Немец называл эту женщину… Беккер слегка потряс Клушара за плечи, стараясь не дать ему провалиться в забытье.

 Двести тридцать восемь? - воскликнула Сьюзан.  - Разве мы не знаем, что в хиросимской бомбе был другой изотоп урана. Все вокруг недоуменно переглянулись. Соши лихорадочно прогоняла текст на мониторе в обратном направлений и наконец нашла то, что искала.

 Estas ya muerto, - тихо прошептал он, двигаясь по центральному проходу. Ты уже мертвец.
