Electron circuits: semiconductor laser multiple use installation
A light source for a multiple use installation using a same matter junction or different matter junction GaAlAs/GaAs semiconductor laser, which has the advantages of high interference resistance, long transmission distance (tens to hundreds of meters), good security, and low power consumption in addition, the controller of the light source has multiple usages of alarming, switching and counting is presented. The multiple use installation can be used in control of breaking warps and counting on roving waste machines, warping machines and silk weaving machines in the textile industry long distance speed measurement, alarming and counting in machinery, electricity and chemical industries and alarming and control of water levels in reservoirs, rivers and water towers, as well as blockade alarming and control of important divisions. This multiple use installation is composed of two parts a laser emitter and a receiving device. The former component is used to produce the laser after the receiver receives the laser, the installation completes operations of alarming, switching and counting.
