摘要： An optical modulator (30) is hung from a key (2a, 2b) moved on a key trajectory so as to be moved together with the key (2a, 2b), and a light beam (B, B1, B2), which is stationary with respect to a key bed (6a), is radiated through the optical modulator (30); a large number of miniature refractors (32c) are formed on the light output surface (32b) of the optical modulator (30), and the density of miniature refractors (32c) per unit area is varied in a direction in which the optical modulator (30) is moved together with the key (2a, 2b) so that the current key position is converted to the amount of light passing through the optical modulator (30); since the miniature refractors (32c) and other portions of optical modulator (30) have a unitary structure, a molding process is used for the optical modulator (30), and the molding process make the production cost low.

摘要： The present invention provides a method and an apparatus for detecting a position of a light spot in a light distribution that can include stray light components (e.g. from other lasers, ambient lighting etc.). The apparatus includes a continuous response position sensitive detector (CRPSD, e.g. lateral effect photo-diode) for determining a first centroid of the light distribution and a discrete response position sensitive detector (DRPSD, e.g. multiplexed array) for determining a second centroid of the light distribution within a reading window defined about the first centroid and within the light distribution. The second centroid represents the position of the light spot in the light distribution. This multiple stage approach exploits the high resolution and speed offered by traditional CRPSDs together with the accuracy under variable lighting conditions offered by traditional DRPSDs.

摘要： An optical device (20) and methods thereof are described. The device includes a first light source (22) adapted to emit light onto a surface (16), and a detector (14) adapted to receive light reflected from the surface. The reflected light produces a speckle pattern. The distance between the optical device and the surface can be measured using a quantifiable attribute associated with the speckle pattern, e.g. average speckle size, the number of speckles in the speckle pattern or the brightness of the speckle pattern.

摘要： According to the present invention, in order to improve the accuracy of the absolute value of a wavelength of diffraction light in the diffraction grating, a gas absorption line resulting from an absorption cell 8 is used as a wavelength reference 8. When reference light is exited from a light source 7 in a wavelength reference light source 1, the reference light is transmitted to a diffraction grating 2 as transmitted light having a spectrum absorbing only light of a predetermined wavelength by the absorption cell 8 to allow it to be reciprocated in a predetermined angle range. The diffraction grating 2 produces a split light beam from the transmitted light from the absorption cell 8. The diffraction grating 2 splits the transmitted light from the absorption cell 8 to provide diffracted light and the diffracted light from the diffraction grating 2 is received by the reference light receiving unit 3. It is possible to, without being affected by a variation in the environmental condition, accurately know the rotation angle of the diffracting grating 2 from the diffracted light of the absorption line-existing waveform component received by the reference light receiving unit 3, that is, the rotation angle of the diffraction grating 2 at a wavelength at that time.

摘要： A position sensor for monitoring the position of the valve element (7) of a valve is described. The sensor comprises reflector means (2) associated with the valve element (7) and arranged to reflect energy, for example visible light, from a suitable source (3) such that when the valve element (7) is in a first position the reflected energy is incident upon a detector (4). Movement of the valve element (4) away from the first position results in the reflected light no longer being incident upon the detector (4). The invention further relates to a valve including such a position sensor.

摘要： A system for measuring the angle of a beam of light is arranged so that a periodically varying pattern is formed on a photodetector (11), with a waveform property such as wavelength or phase of the pattern varying with the angle of the light. This may be done by creating interference between the light beam to be measured and a reference light beam having a fixed angle, or by forming a shadow on the detector array (11) of one or more masks (23, 25) having a periodically varying transmission characteristic. One convenient way of processing the output of the photodetector array is to perform a fast Fourier transform, obtain therefrom one or more spatial frequency components, and extract therefrom a part which provides a measure of the angle of the light beam. The use of a periodically varying pattern on the photodetector array (11) enables a substantial length of the array to be used in any particular measurement operation, and averages out individual performance differences between different elements of the photodetector array (11). The use of waveform properties enables convenient signal processing to be carried out, for example using well known fast Fourier transform techniques.
