摘要： A micromachine and a method of manufacturing the same which are suitable as or for a micromachine having a first dynamic fine structural portion constituting a driving portion, and a second static fine structural portion performing a switching function or a function of an optical element, the method comprising forming the second static fine structural portion on the first dynamic fine structural portion, or superposing the second static fine structural portion thereon and die transferring the same thereto, whereby the method enables the second fine structure to be formed without using at least a complicated step, such as a silicon process in an intermediate stage of the method, and into a complicated shape easily with a high reproducibility, and contributes to the improvement of the productivity. Especially, when a plurality of elements are arranged in an arrayed state as in a spatial light modulator, the die transfer techniques enable the second fine structure to be reproduced stably as compared with the techniques using a silicon process for forming all parts of a micromachine, whereby the subject method reduces the probability of occurrence of defects to a remarkably low level and contributes to the improvement of the yield.

摘要： There are provided a spatial light modulation device and a projector capable of obtaining smooth image quality so that an observer does not recognize any light shading portion such as a black matrix. The projector includes a spatial light modulation device (110R) for modulating the incident light according to an image signal and emitting the modulated result and a prism group (210) arranged at the emission side of the spatial light modulation device (110R). The spatial light modulation device (110R) has an opening (230) as a plurality of pixel portions arranged in a matrix and a black matrix (220) arranged between them. The prism group (210) consists of a prism element (211) having at least a refraction surface (212). Light from one opening (230) is introduced into at least a part of the prism group (210). The direction of the refraction surface and the inclination angle ϑ are defined so as to introduce an opening image (230P) onto a black matrix portion image (220P) on a screen (116) at a predetermined distance L from the prism group (210).

摘要： A plurality of slant faces (1419) are formed on a substrate (1406). A polarized optical thin film is formed on the slant faces. The recess defined by the slant faces (1419) is filled with transparent material to form a small composite polarizing element. By this polarizing element, it is possible to detect magneto-optic signals excellent in transmissivity and extinction ratio and high in S/N ratio. Also, this polarizing element serves as the cover of the package (1408) of an optical head which houses a photodetecting element (1409) and a light emitting element (1411) integrally. Also, by use of an optical element having an optical path length adjustment function of varying the optical path length of the outgoing light beam from that of the incoming light beam, it is possible to eliminate the initial offset of the focal point error signals and to omit the adjustment at the same time. In this way, a small, simple and high-performance optical head used for magneto-optic recording and reproducing apparatus can be realized.

摘要： A light guide part which can reflect a light totally and transfer the light, an optical switching part which has its extraction plane close to a totally reflective plane to capture an evanescent light and reflects and emits the evanescent light and a driving part which drives the optical switching part are layered in the direction of the light emission in this order to obtain an optical switching device with a hierarchical structure. By employing the hierarchical structure, the respective layers can be optimized. Especially, as the extracted light is not passed through the driving part, the driving part can be optimized to provide an optical switching device which can operate at a high velocity and with a low power consumption. Therefore, an optical switching device which shows the low loss of a light utilizing an evanescent wave, has a high response velocity and, further, shows a large contrast ratio can be provided.

摘要： An image display has a light guide having a total reflecting surface which reflects guided light for image display totally transmits the light and an optical switch having a microprism which extracts the evanescent light leaking from the total reflecting surface and reflects it. Guided light is directed from two directions symmetrical with respect to a display area to produce light from the whole surface of the microprism. Therefore, an image display on which a brighter image having a higher contrast can be displayed is provided, by optimizing the vertex angle of the microprism, the directions of emitted rays of light are matched and directed vertically to the total reflecting surface, so that an image display which displays a high quality image is realized.
