Acousto-optical spectrometer
text:
An acousto-optical spectrometer (AOS) is based on the diffraction of light by ultrasonic waves. A piezoelectric transducer, driven by the RF signal, generates an acoustic wave in a crystal. This acoustic wave modulates the refractive index and induces a phase grating. The Bragg-cell is illuminated by a collimated laser beam. The angular dispersion of the diffracted light represents a true image of the IF-spectrum according to the amplitude and wavelengths of the acoustic waves in the crystal. Th
