WebThe Acousto -Optic Modulator is based on the elasto -optic effect, in which a material strain causes a change in the refraction index of the material. When the strain is generated by an acoustic compression or rarefaction, an AOM is formed. Because the acoustic signal is sinusoidal, a moving refractive index grating is formed in the device. WebRF Drivers for Beam Deflectors In contrast to an acousto-optic modulator, a beam deflector requires an RF driver with constant drive power but variable frequency. Often, it contains a voltage-controlled oscillator …
