An illuminator includes: a light source section including a laser light source; an optical element through which a laser beam from the laser light source passes; a driving section oscillating the optical element; and a control section controlling, in a driving operation performed by the driving section, the driving operation to allow an oscillating amplitude value of the optical element in a startup period of the optical element to be equal to or less than the oscillating amplitude value of a steady-state operation period of the optical element that is subsequent to the startup period. |
