| Acousto Optical Spectrometer Acousto Optical Spectrometer An Acousto Optical Spectrometer is based on the diffraction of light at 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... (AOS) |
