Abstract: An actuator drive device is configured to drive an actuator. The actuator drive device includes a storage section for storing a drive condition of the actuator, a processor for calculating and outputting drive signal D(t) based on a drive base signal V(t) calculated based on the drive condition with respect to time t, and a generator for outputting, based on the drive signal D(t) calculated, a driving signal for driving the actuator. The drive base signal V(t) is a sum of a fundamental wave and at least one harmonic wave of the fundamental wave. The processor is operable to determine the coefficient ak such that the drive base signal V(t) changes linearly from a minimum value to a maximum value with respect to a time. This actuator drive device improves the linearity of the driving of the actuator.

Abstract: A scanning mirror includes a mirror unit configured to reflect a laser beam, a supporter configured to cause the mirror unit to rotate and oscillate, and an oscillation sensor configured to output a monitor signal indicating oscillation of the mirror unit. A photodetector detects an intensity of the laser beam. When a value of the monitor signal falls out of a predetermined range of a normal operation and a value of the intensity detected by the photodetector fails to decrease, a breaking signal for causing the supporter to oscillate more than a breaking limit angle of the supporter is input. This scanning mirror and an image projection device using this scanning mirror can display an image at sufficient brightness safely.
