Abstract

An optical scanning device includes: a micromirror device, a first actuator that allows the mirror portion to swing around a first axis, and a second actuator that allows the mirror portion to swing around a second axis orthogonal to the first axis; and a processor that causes the mirror portion to perform precession by providing a first driving signal and a second driving signal each having the same driving frequency to the first actuator and the second actuator, respectively. In the micromirror device, a relationship of f<fis satisfied in a case in which a resonance frequency around the first axis is denoted by fand a resonance frequency around the second axis is denoted by f, and a relationship of f≤fis satisfied in a case in which the driving frequency is denoted by f.
