The transducer for a broadband acousto-optic scanner appears as a capacitor in parallel with a resistor corresponding to the acoustic energy conversion. In general, the 'reactive power' will dominate the driver requirements. In the case of an acousto-optic scanner, a single swept frequency is sup-plied, which gives a knowledge of the frequency at any instant.
