摘要： A light deflection element has a pair of transparent substrates 2, 3; a chiral smectic C phase liquid crystal 5 with a homeotropic alignment filled between the pair of transparent substrates 2, 3; and at least an electric field applying device 6 for activating an electric field in the liquid crystal 5. Because a chiral smectic C phase liquid crystal is used, the problems of the conventional light deflection element, such as high cost, light loss, large size, and optical noise etc. due to its complicated structure, can be greatly improved. The conventional low response time due to the smectic A phase or the nematic liquid crystal is improved, thereby the high-speed response is possible.

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： A magneto-optical recording method for recording information in an overwrite mode in a magneto-optical recording medium by the application of a laser beam is disclosed. The magneto-optical recording medium includes a substrate, and at least two magnetic recording layers overlaid thereon, with an exchange force working at least between the two magnetic recording layers, and the Curie temperature of each of the two magnetic recording layers being substantially the same. The magneto-optical recording method includes the step of conducting overwriting information by changing the power of the laser beam to be applied to at least two different levels, one at which the magnetic recording layers are heated to a temperature near or higher than the Curie temperature, and the other at which the magnetic recording layers are heated to a temperature lower than the Curie temperature, while a magnetic field is applied to the magneto-optical recording medium in one direction, in accordance with signals to be recorded in the magneto-optical recording medium, and this recording method requires only one initialization by the application of the magnetic field, but does not require any further initialization thereafter.
