    Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for measuring temperature capable of easily forming a differential image which is high in reliability even in the case that among a plurality of thermal images the imaging view fields are deviated.
    SOLUTION: Feature-points 41, 42 and 43 in a thermal image 10 of a mold 1 for metal casting are extracted, based on the coordinate of the feature-points 41, 42 and 43 and the coordinate of reference feature-points 61, 62 and 63 set in a reference thermal image 30 which are previously imaged, the corrected thermal image 20 is created by processing the thermal image 10 with any one or ≥2 of rotation, translation and zooming processes so that the feature-points 41, 42 and 43 are made to overlap on the corresponding reference feature-points 61, 62 and 63. The differential thermal image 40 being difference of the corrected thermal image 20 and the reference thermal image 30 is created by over lapping the corrected thermal image 20 on the reference thermal image 30 so as to overlap the corrected feature-points 51, 52 and 53 in the corrected thermal image 20 on the corresponding reference feature-points 61, 62 and 63.

    Abstract: There is provided a laser energy measuring unit whose laser energy measuring range is widened. The laser energy measuring unit has a filter provided within an optical path of a laser to attenuate energy of the laser, a calculating section for measuring the energy of the laser passing through the filter, and a condenser lens provided on one side of the filter for condensing the laser. The filter has a shading portion for blocking a center part of the laser beam from being transmitted through the filter at a position coincident with the center of the laser. The center part of the laser where its energy is large is cut by the shading portion, and the calculating section measures the part where its energy is not so large. Thereby, it is possible to widen the laser energy measuring range.

    Abstract: PROBLEM TO BE SOLVED: To stabilize light emitted from a light source in a system, a method and an apparatus for regulating light emitted from a light source. SOLUTION: A control system 212 has a driver circuit 302, a color management system 304 and a micro controller 306. Boundaries among these components can be arbitrarily set and also functions of the components can be merged alternately to divide them. The color management system 304 receives the color and/or intensity setting contents from the controller 306 to convert the color setting contents into a plurality of intensity setting contents for light-emitting elements different in color of a light source 202. The management system 304 receives a intensity measured value from a photosensor 208. The management system 304 compares each measured value with one another, and if the measured values are out of a range, regulates light outputs of the corresponding light-emitting elements, for instance, by modulating drive currents.

    Abstract: PURPOSE:To obtain the photo detection angle characteristic complying with the cosine law, by providing one or more photo detection angle characteristic correcting apertures on the side of a photo detector. CONSTITUTION:Light incident from the top (x) of a light diffusion plate 3 reaches a photoelectric conversion element 7 passing sequentially through a magnifying filter 5 and a view angle correction filter 6 to be converted into electricity. As the photo detection angle grows larger to 90 deg., incident light from the top (x) of the light diffusion plate 3 decreases too much to maintain the photo detection angle characteristic complying with the cosine law. But when provided on the side of the substrate 4, an aperture 8 allows light to reach the BD surface incident from the AC surface so that the photo detection characteristic is corrected with respect to the photo detection angle near 90 deg.. In this manner, the photo detection angle characteristic can be obtained which the light receiving surface composed of the substrate 4 and the light diffusion plate 3 is flat while precisely complying with the cosine law.
