FIELD: optics. SUBSTANCE: laser autocollimation centering mount for X-ray radiator includes body housing laser which optical axis is parallel to longitudinal axis of X-ray radiator, two mirrors, first being made of acrylic plastic and is installed at crossing point of optical and X-ray radiation beams, perpendicular to plane formed by them and directing collimating laser beam on object, scale, telescope comprising microlens and lens enabling actual image of luminous disc generated on surface of object in zone of illumination by laser beam to be formed in focal plane of lens of telescope coinciding with linear scale of glass with the help of first mirror of lens and second semi-transparent mirror. Image of scale and zone of object illuminated by laser beam is projected on to plane of miniature CCD matrix of TV camera, video signal from it is fed to input of video control unit on which screen image of laser spot is observed. Size of laser spot determines value of focal distance of X-ray radiator for its particular position with reference to object. Centering mount also has separable mirror placed on object in zone illuminated by collimated laser beam and forms autocollimation circuit controlling mutual angular orientation of object and centering mount together with telescope, laser and scale. EFFECT: possibility of control of perpendicularity of axis of X-ray beam and surface of tested object. 1 dwg |
