Abstract

The present disclosure describes a circuit to control acousto-optic modulators for measuring electrophoretic mobility. In an embodiment, the circuit includes at least two channel amplifier circuits, a radio frequency generator logically coupled to the channel amplifier circuits, where the radio frequency generator is to output drive signals to the channel amplifier circuits, a synchronized data acquisition system logically coupled to the radio frequency generator, where the synchronized data acquisition system is to digitize an optical signal from a photo diode logically coupled to at least two acousto-optic modulators, and where one of the channel amplifier circuits is to drive one of acousto-optic modulators and the other of the channel amplifier circuits is to drive the other of the acousto-optic modulators, where the acousto-optic modulators and photo diode are to measure electrophoretic mobility of a sample.
