Abstract
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.
Claims19
An illuminator, comprising:
- 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.
A display unit, comprising:
- an illuminator emitting illumination light;
- and
- an optical modulation element modulating the illumination light based on an image signal,
- wherein the 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.
