ACTUATOR CONTROLLING DEVICE, DRIVE SYSTEM, VIDEO DEVICE, IMAGE PROJECTION DEVICE, AND ACTUATOR CONTROLLING METHOD

摘要

An actuator controlling device controls an actuator based on signals acquired from a photodetector. The actuator includes a drive unit that causes a reflecting part to move. The actuator controlling device includes a waveform generating unit, a driving amplifier, a power supply unit, and a controller. The waveform generating unit generates a voltage waveform for driving the drive unit. The driving amplifier amplifies the voltage waveform generated by the waveform generating unit. The power supply unit supplies power to the driving amplifier. The controller acquires detection signals from the photodetector and controls, based on the acquired detection signals, voltage to be supplied from the power supply unit to the driving amplifier.
