    摘要： An optical deflection device includes an optical deflection element having a pair of transparent boards arranged in a mutually opposing manner. A liquid crystal layer is filled between the boards and forms a chiral smectic C phase. An orientation film orients liquid crystal molecules in the liquid crystal layer in a substantially perpendicular direction with respect to the liquid crystal layer. Electrodes generate an electric field in a substantially parallel direction with respect to the liquid crystal layer. A first voltage application part applies, to the electrodes, an ac voltage of a deflection frequency switching the optical deflection direction of the optical deflection element. A second voltage application part applies, to the electrodes, an ac voltage of a higher frequency than the deflection frequency. A stop process part causes the second voltage application part to apply the ac voltage of the higher frequency than the deflection frequency after causing the first voltage application part to apply the ac voltage of the deflection frequency, when stopping an operation of switching the optical deflection direction of the optical-deflection element.

    摘要： An image display apparatus acquires a high-quality image by suppressing positional fluctuation of projected dots due to a positional offset of an optical path deflecting element. A spatial light modulation element (1) displays an image by projecting a light from an illumination light source. A projection optical system (3) enlarges and projects the image formed on the spatial light modulation element (1). An optical path deflecting element (2) is provided between the spatial light modulation element (1) and the image formed on a screen (4) so as to deflect an optical path in accordance with a screen frame period. The optical path deflecting element (2) shifts the optical path for the image projected on the screen (4) at a high rate so as to apparently increase a number of picture elements. The optical path deflecting element (2) is located within the projection optical system.

    摘要： An imaging unit images light on a light receiving element, and includes an optical path shifting element, and a lens arranged on an input side or an output side of the optical path shifting element. The optical path shifting element includes a liquid crystal layer which is applied with an electrical field in a direction approximately parallel to an in-plane direction. The liquid crystal layer is made of a chiral smectic C phase ferroelectric liquid crystal having a homeotropic alignment. The optical path shifting element shifts an optical path of the light input thereto in an optical path shifting direction.

    摘要： In a method for displaying a three-dimensional stereo image, a left-eye image defined by multiple left-eye strip pixels and a right-eye image defined by multiple right-eye strip pixels are displayed such that the left-eye pixels and the right-eye pixels are arranged alternately from the left to the right in a width direction. The left-eye image and the right-eye image are guided separately to the left eye and the right eye of an observer. Then, the left-eye image and the right-eye image are shifted by one pixel in an oscillating manner, and the left-eye image and the right-eye image are deflected synchronized with the one-pixel shifting operation.
