Abstract: A light deflection element is capable of deflecting incident light so as to follow a position of an observer and suppressing reduction in intensity of light that reaches eyes of the observer regardless of their position. The light deflection element includes: a first optical element configured to deflect incident light; a second optical element configured to change a deflection direction of emitted light by changing a refractive index thereof according to a voltage applied thereto; a third optical element; and a control section configured to control the voltage applied to the second optical element. At least one of interfaces between the first and second optical elements and the second and third optical elements is an aspheric surface. The aspheric surface has an optical power that compensates enlargement of the emitted light which is caused by refractive index distribution caused when a voltage is applied to the second optical element.

Abstract: An optical resonator includes: a light source that emits light; a diffractive element that diffracts the light emitted at the light source and incident thereon as s-polarized light; and an output coupler that resonates the s-polarized light diffracted by the diffractive element. The output coupler includes: a mirror arranged to reflect the light from the light source via the diffractive element; a polarization beam splitter arranged on a light path between the diffractive element and the mirror, and emitting, out of light incident thereon after emitted from the mirror, a p-polarized component to return to the light source and a s-polarized component as the output light; a quarter-wave plate arranged between the polarization beam splitter and the mirror, and having an optical axis providing a phase difference by a quarter wavelength in light incident thereon; and an adjuster that adjusts a direction of the optical axis of the quarter-wave plate.

Abstract: An image display apparatus includes a display device, a parallax barrier, and a controller. The display device displays an image for right-eye and an image for left-eye, with the images having a parallax amount between them. The parallax barrier directs, toward a right eye and a left eye, light of the images which are output from the display device. The controller controls the display device such that the display device continuously varies the parallax amount and the luminance of the displayed images and switches between a mode of showing the images to the both eyes and a mode of showing the corresponding image to any one of the eyes.
