摘要： A projection linear encoder has an SOQ substrate formed with transmission gratings and grid-like photodiode groups, and a reflecting grating plate with reflecting gratings that are formed facing thereto. A light-blocking film composed of a metal thin film or the like is formed on a surface of a glass substrate of the SOQ substrate, and the transmission gratings are formed by patterning the light-blocking film. The photodiodes are integrally formed by epitaxial growth on the silicon layer of the SOQ substrate. Transmission gratings with high mechanical strength can be formed inexpensively in comparison with cases in which through holes are formed by etching a silicon substrate to manufacture transmission gratings.

摘要： The hinge (13) should preferably be formed to have a higher resistance than ever against the pivoting of the mirror body (12) to effectively prevent the hinge (13) from being damaged. By adopting a suitable one of a variety of production steps as necessary, the hinge (13) can be formed more finely and with a higher precision and thus the micro mirror unit can be produced more easily in a shorter time. To this end, the hinge (13) is formed from a different material, such as SiNX, from the mirror substrate material from which the frame (11) and mirror body (12) are formed.

摘要： In an optical linear encoder, light from an LED 2 passes through a moving grating 31 formed in a semiconductor moving plate 3 and is reflected by a reflective grating 41 of a reflective grating plate 4. An image of the reflective grating is detected by photodiodes 32 that are formed in the shape of a grid on the semiconductor moving plate 3. The moving grating 31 and the photodiodes 32 are formed on the same semiconductor substrate with the photodiodes 32 in the form of a grid having a lens effect. Consequently, a lens optical system is not required, making it possible to produce a compact, small-scale encoder. A differential signal for an A-phase signal obtained from a group of photodiodes arranged on the semiconductor substrate and an inverse of this signal is produced as the A-phase signal, and a differential signal for a B-phase signal and an inverse of this signal is produced as the B-phase signal, so that an encoder output with little error can be obtained.

摘要： To make an optical switch smaller, two frames are formed by etching in such manner that when they are stuck together to form a support member, an hexagonal opening appears. The end portions of a pair of fixed optical fibers are arranged in the bottom portions of a pair of opposing V-grooves provided in this hexagonal opening. A pair of movable optical fibers are fixed at the other end of the support member, and these movable optical fibers are arranged in such manner that their end faces are contiguous with the end faces of the pair of fixed optical fibers. A drive mechanism causes the end portions of this pair of vertically arranged movable optical fibers to move to the left or the right, come into contact with the walls of respective V-grooves, slide into the bottoms of the grooves, and thereby have their cores aligned with the cores of the fixed optical fibers. Alternatively, two parallel beams formed from silicon are formed on the inside of a single frame, a pair of mutually opposing projections are formed in approximately the middle portions of these beams, and the end portions of a pair of optical fibers are arranged in and in contact with V-grooves formed parallel to and on the opposing faces of this pair of projections.

摘要： A first laser beam is modulated at a modulation frequency and focused on a first point in the proximity of a connection being tested so as to generate a photothermo elastic wave thereat, and a second laser beam is focused on a second point in the proximity of the connection, which second point is separated from the first point. The second laser beam is scattered at the second point. A detector detects a modulation-frequency component of the scattered second laser beam, so as to detect a propagated level at the second point of the photo-thermo elastic wave from said first point based on the detected modulation-frequency component of the scattered second laser beam. The propagation of the elastic wave depends on the strength of the connection and the detected level of the elastic wave indicates strength of the connection.
