摘要： An optical scanning device comprises an optical system for imaging a part of the surface (10) to be scanned on the detection system (22-25; 122-125). The optical system comprises an objective system (43) and two cylindrical lenses (41, 42) and/or two systems of cylindrical mirrors (141a, 141b, 142a, 142b). In the direction in which the cylindrical lenses (41, 42) have their optical power, the objective system (43) functions as an imaging lens so that a light-intensive and spatial image of the surface is formed at the detection system (22-25). Due to the achieved large numerical aperture, the image formed can also be observed three-dimensionally so that information about the profile of the surface can be obtained by means of the scanning device.

摘要： An on-line method of and apparatus for inspecting an apertured mask sheet to be formed into a shadow mask for a color cathode ray tube are disclosed. In one of several embodiments described the mask sheet is linearly scanned by a laser spot transverse to the direction of advancement of the mask sheet. The peak values of the grey levels of the laser light transmitted by the mask sheet are detected and the data is convoluted electronically to form a series of convolution windows. The grey levels of the successively formed convolution windows are compared to at least one reference value and an output is produced at least in those cases where an error in the mask aperture size is detected.

摘要： A device for optically measuring the height of surface irregularities of an object. A scanning spot of radiation (11) is formed on such surface, and a first optical imaging system (20) forms a reflected image (31) of the scanning spot on a diffusely reflective or transmissive screen (30). A second imaging system (40) forms from the imaged scanning spot (31) a re-imaged scanning spot (51) on the photosensitive surface of a position-sensitive radiation detection system (50). The screen is arranged so that the radiation from scanning spot (11) is incident thereon at a small grazing angle, and is adapted to diffuse the radiation from the imaged scanning spot (31) to produce radiation directed substantially normally on the photosensitive surface of the radiation detection system. A high degree of correlation between the position of the re-imaged scanning spot (51) on the photosensitive surface and the height (.DELTA.Z) of the surface of the object being measured is thereby achieved. The substantially normal direction of incidence of radiation on the photosensitive surface minimizes reflection therefrom and so improves the efficiency of the radiation detection system.

摘要： A hair-removing device (1) includes a laser source (3), an adjustable laser beam manipulator (5) for positioning a laser beam (7) of the laser source (3) in a target position (9) on a skin (11) to be treated, and an image sensor (47) for detecting an image (49) of the skin. The hair-removing device further comprises a control unit (17) which determines a position and orientation on the skin of a hair (13) to be removed, and which determines the target position of the laser beam as a function of said position and orientation of the hair. The control unit brings the laser beam manipulator in a state corresponding to the target position of the laser beam, and activates the laser source when the laser beam manipulator has reached said state. Thus, the hair-removing device is suitable for use by inexperienced users, and is particularly suitable for the consumer market. In a particular embodiment, the control unit determines the target position of the laser beam in a position (71) on the skin under which a root (15) of the hair is present, so that the root of the hair is destroyed and the hair-removing device (1) is an epilating device by means of which the hair is removed for a relatively long time or even permanently. In another embodiment, the control unit determines the target position of the laser beam in a position (65) on the hair where the hair comes out of the skin, so that the hair is burnt through near the skin surface and the hair-removing device (1″) is a shaving device by means of which a high skin smoothness is obtained.
