Acousto-optics is a branch of physics that studies the interactions between sound waves and light waves, especially the diffraction of laser light by ultrasound or sound in general.- Category ID : 428762
Article from Wikipedia on this branch of physics that studies the interactions between sound waves and light waves, especially the diffraction of laser light by ultrasound or sound in general.
The principle of operation of these filters is based on the dependence of the diffracted light wavelength on the acoustic frequency. This article considers non-collinear filters based on a single TeO2 crystal.
