    • PURPOSE: A fringe pattern discriminator for interferometer using diffraction gratings is provided to analyze the interferogram produced in the interferometer using a pair of diffraction grating, which separate and reunite both test beam and reference beam for measurement the surface of object. CONSTITUTION: The interferometer separates reference and test beams which can measure the total surface of object arranged between diffraction gratings. The positive order beam, negative order beam, zero order beam passing gratings are generated by the composition of gratings and object surface. An object fringe pattern is distinguished from other fringe patterns in an interferogram produced by an interferometer using a pair of diffraction gratings for separating and recombining test and reference beams. The object on which a test beam is incident is moved in X and Y directions in a plane perpendicular to an optical axis of the interferometer to change the brightness regions of the object fringe pattern. A computer identifies pixels whose irradiance changes in response to object movement, and then only irradiance data from the identified pixels is used in analyzing the interferogram to produce a measurement of a surface of the object.

    • PURPOSE: An object fixturing in interferometer is provided to improve accuracy of positioning establishment and to let the object situated in interferometer of the same measured position. CONSTITUTION: The object fixturing system applied to an interferometer which has a pair of diffraction gratings arranged to produce and recombine test and reference beams. The object positions between diffraction gratings so that a test beam is incident on a surface of the object at a grazing incidence angle. The object platform which is arranged movably between diffraction grainings has the window supporting object and transmitting a test beam. The fixture is then removed for a simultaneous measurement of an entire surface of the object, which can be clamped in place if necessary by a clamping window that also transmits the test and reference beams.

    • A spatial phase shifter for a real-time optical interferometer is provided to measure interference in real time by making phase-shifted interference patterns identical and to improve utility by applying the phase shifter for all interferometers. A spatial phase shifter for obtaining plural interference patterns, which are phase-shifted by 90 degrees, includes an optical path compensation block for matching optical paths of corresponding emitted lights to obtain plural interference patterns; and a distortion preventing block(500) for restricting image distortion of the interference pattern by equalizing the ends of the emitted lights output from the optical path compensation block. The optical path compensation block is a glass block with a refractive index equal to the refractive index of a medium positioned in the optical path.

    • PURPOSE: A phase transition diffraction grating interferometer and a measuring method thereof are provided to measure an object by adopting an interference pattern obtained from an optical system to a phase transition algorithm. CONSTITUTION: A light source(43) radiates light through a lens(53) and an aperture(63). A lens(73) makes parallel light and lens(83) allows parallel light to be focused on a reflective diffraction grating(103). Light incident into the reflective diffraction grating(103) is split into several parts. One of them is reference light(233) and other light(223) forwards to an object to be measured. Light passing through a lens(113) and an iris(123) forms an image on an image obtaining device(23). The image obtaining device(23) includes a CCD camera. A CPU(13) controls a phase transition driver so as to allow the phase transition to apply a signal to a phase transition generator(153).
