Application of Acoustical Activity for Control of Light Intensity

Annotatsiya

The proposed new technology is differed from all the existing technologies for measuring and control of light intensity. In the proposed method is used the Bragg light diffraction on the hypersonic wave in gyrotropic crystals. The light intensity can be changed by modification of generator frequency by which the acoustic wave is excited. The increase or decrease of light intensity is provided electronically, fluently and with high accuracy. Using previously the standard calibration, it is possible to measure and change the light intensity to the necessary value.
