摘要： A system for interferometric fit testing of a specimen having an aspherical surface in reflection, the specimen being a segment (2) (footprint) of a rotationally symmetrical basic body (1) (parent), comprises an interferometer (3) and a diffractive optical element (DOE) (5). An optical axis of the interferometer (3) in the beam direction behind the diffractive optical element (5) and an axis of rotation of the basic body (1) form an angle that differs from zero. The diffractive optical element (5) is designed in such a way that the rays produced by the interferometer (3) and falling into the diffractive optical element (5) strike the specimen (2) perpendicularly and from there run back in themselves.

In an off-axis holographic optical image pick-up device (100), object beams (L1) that is a flux of parallel beams are irradiated onto particles (114) as a subject. At the same time, reference beams (L2) are incident, with an inclination, onto the object beams (L1) after being irradiated onto the particles (114). An interference fringe generated as a result of the interference between the object beams (L1) and the reference beams (L2) is recorded onto a recording material Noise elimination relay lenses (116a and 116b) are installed between the particles (114) and the recording material (115). Further, a noise elimination pinhole plate (117) having a pinhole (118) is installed between the lenses (116a and 116b) constituting the relay lens.

摘要： 1. Method and apparatus for testing objects. 2.1 With interferometric test systems, the test object is frequently measured over several sections in order to realize a complete test. If special structural features are found, in particular defects, it is usually difficult to localize the structural features shown on the result images on the object. 2.2 It is the object of the new method to transfer the interferometrically measured data from the various sections to a joint object coordinate system. To achieve this object, the shape of the object is measured and the spatial coordinates for the deformation data on the object surface are determined from this. 2.3 Thus, a method is realized with the invention, which permits determining the exact spatial orientation and position of the discovered structural features on the object. On the one hand, the defects on the object can thus be localized precisely while, on the other hand, an exact quantitative evaluation of the results is possible.

摘要： Multi-domain, phase-compensated, differential-coherence detection of photonic signals for interferometric processes and devices may be manufactured holographically and developed in situ or with an automatic registration between holograms and photonic sources in a single frame. Photonic or electronic post processing may include outputs from a cycling or rotation between differently phased complementary outputs of constructive and destructive interference. A hyper-selective, direct-conversion, expanded-bandpass filter may rely on an expanded bandpass for ease of filtering, with no dead zones for zero beat frequency cases. A hyper-heterodyning, expanded bandpass system may also provide improved filtering and signal-to-noise ratios. An ultra-high-resolution, broadband spectrum analyzer may operate in multiple domains, including complex nullfingerprintsnull of phase, frequency, and other parameters. The associated technologies of the invention may be used to produce extreme precision in multi-domain locking of sophisticated waveforms varying in several domains. Phase-masking techniques may provide phased arrays of complementary outputs over a broad band, such as may be implemented in a projected phase-mask, multiple phase interferometer. Topographic holographic imaging and projection techniques are enabled at very fine resolutions, while minimizing required information for systems such as holographic television. Phase-stabilization, modulation, compensation and the like are enabled by devices and methods in accordance with the invention, and may be servo-controlled.
