摘要： An optical head and an optical recorder with which data can be recorded/reproduced onto/from a conventional CD-R without a problem and, further, data can be recorded/reproduced onto/from an optical recording medium of DVD standard which meets the requirements of the high recording density by employing a semiconductor laser beam which has a relatively longer wavelength than the track pitch of the optical recording medium and the optical super-resolution technique. Moreover, since a semiconductor laser beam which has a relatively longer wavelength than the track pitch of the optical recording medium can be employed by the optical head and the optical recorder, the limitation of the high density recording can be broken through and the optical pickup device and the optical recorder can record/reproduce data of the high recording density at a low cost and with the high reliability and can meet the requirements of the much higher recording density in future.

摘要： A display device includes a first diffraction element (61) configured to diffract image light and a second diffraction element (35) disposed on an optical path between a light source (51) and the first diffraction element (61). The first and the second diffraction elements (61,35) emit light beams that have highest diffraction efficiencies in one direction when a single wave light enters from directions of normals to the first and second incident planes (615) and (355). If the sum of the number of reflections of light and the number of times of intermediate image generation between the second diffraction element and the first diffraction element (respectively 35 and 61) is an even number, the directions of the diffraction light having the highest diffraction efficiencies when light enters from the directions of the normals to the diffraction elements (61,35) are the same with respect to the directions of these normals to the incident planes. If the sum is an odd number, the directions are different.

摘要： A picture display device in accordance with the present invention is provided with a light guiding member equipped with a total reflection surface capable of totally reflecting and transmitting an incoming light ray for image display, and an optical switching member having a micro prism that extracts evanescent light leaking out of the total reflection surface and reflects it to a display area of the total reflection surface. The incoming light ray is applied to the display area from two symmetric directions so as to obtain outgoing light rays from all surfaces of the micro prism. Hence, a picture display device featuring still higher brightness and higher contrast can be attained. Furthermore, an apex angle of the micro prism, etc. are optimized thereby to provide further uniform outgoing light arranged perpendicularly with respect to the total reflection surface, thus realizing a picture display device capable of displaying high-quality images.
