Abstract
An electric circuit for driving an acousto-optic crystal includes a piezoelectric converter configured to drive the acousto-optic crystal to vibrate mechanically. A signaling cable is configured to conduct a first electrical alternating-current signal and a second electrical signal. The electric circuit further includes a first frequency-separating filter and a second frequency-separating filter, each of the frequency-separating filters having an input, a high-frequency output and a low-frequency output. The input of the first frequency-separating filter and the input of the second frequency-separating filter is connected to the signaling cable, and the high-frequency output of the second frequency-separating filter is connected to the piezoelectric converter.
