摘要： A displacement information detection apparatus for detecting relative displacement information regarding the apparatus and an object to be detected includes an illumination system for radiating coherent light. A first diffraction grating splits the coherent light from the illumination system into first and second light beams, which are radiated onto the object. A second diffraction grating synthesizes the first and second light beams emerging from the object to generate an interference light beam. A light-receiving element detects the interference light beam and detects the relative displacement information regarding the object and the apparatus upon reception of the interference light beam. The illumination system is configured to focus the first and second light beams at a location along an optical path between the first diffraction grating and the second diffraction grating, so that the interference light beam incident on the light-receiving element is a divergent light beam.

摘要： In an optical displacement sensor for measuring a moving state of a moving object by projecting a light beam onto a diffraction grating provided on a surface of a scale connected to the moving object and utilizing diffracted light beams of specific orders from among diffracted light beams diffracted by the diffraction grating, a portion of the light beams incident upon the diffraction grating is reflected at a reflecting region provided on the back of the scale a plurality of times. A photosensor detects a change in the amount of light emanating from a transparent or a light-blocking reference position, formed on a region on the surface of the scale other than the region where the diffraction grating is formed. An output signal from the photosensor is utilized as a reference signal, which provides information relating to the moving state of the moving object.

The plurality of light beams are guided to a diffraction-grating scale which moves together with an object whose relative displacement is to be measured. Two light beams emanated from the diffraction-grating scale are combined by a second diffraction grating provided on the transparent substrate. A resultant light beam from the second diffraction grating is guided to photosensors. Relative displacement between the transparent substrate and the object is measured using signals from the photosensors. Indices for displaying positional information of a condenser lens provided on the transparent substrate and/or the first and second diffraction gratings are also provided on the transparent substrate. The optical apparatus is used within displacement-information measuring apparatus.

摘要： A mosaic puzzle set has a predetermined number of pieces (45) with unique, directionally visible, identifiers and different brightness characteristics, three for grey scale and five for color, comprising average brightness(es), and direction and magnitude of brightness gradients, enabling assembly to copy any user selected target picture (30) by following a dedicated table/chart (33). An internet server (1) storing piece characteristics and accessible for target picture upload and chart download by an access code in the purchased set, divides (S11) the target picture (30) into a same number of data areas (311) as pieces, analyzes their brightness characteristics and assembles the chart (33) by provisionally assigning pieces to respective target areas (311) and exchanging them for each other when sums of respective mismatch values between pieces and respective target areas are thereby reduced (S12-S14). Alternatively, pieces are divisions of an iconic source picture or only screen images. Pieces in a humped brightness histogram, population distribution provide greater detail. A grid-form tray supports and aligns pieces during assembly. Internet (2) billing is possible.
