摘要
Abstract
The basic principle of Laser monitor has been discussed and its main operational procedure has been introduced.According to the physical and mathematical models suggested by us and others,we have proved that the key factor the laser monitor can work effectively is because of the coupling of the surface waves of the solid state with sounding waves.It has been proved the coupling waves can pass across the windowpane and form stationary waves of micron order.The stationary waves form many scatters for laser,which can modulate the laser beam.By the optical to electrical transducer and electro-acoustical transducer,any sound in the room can be monitored.关键词
