Abstract: The present invention provides the capability of ascertaining, through a quick and simple measurement, locations on a structure that may have experienced damage that could result in reduced structure lifetime, strength, or reliability. The sensing element is a connectorized section of polarization maintaining (“PM”) optical fiber, where a length of PM fiber represents a fully distributed sensor array. Stress-induced changes to the sensor are measured through white-light Polarimetric interferometry. The output of the measurement is a data array representing the stress concentration magnitude at an array of locations along the length of the sensor. In an application, the knowledge of the optical fiber position on the structure, coupled with the measurement of stress locations along the fiber length, allows the user to determine locations on the structure with large stress concentrations. These locations may signify structural damage. This knowledge would allow the user to employ a more sophisticated system, albeit a larger and slower one, to fully characterize and evaluate that area of potential damage and take appropriate action.

Abstract: A method of restoring low spatial frequency spectral information to an image using a Fizeau Fourier transform spectrometer (“FFTS”) system is provided. Portions of a wavefront collected by the FFTS are interfered. The interference patterns are Fourier transformed to generate spectral images. A region of the image is identified, for which spectral information is predetermined. Object estimates are generated, each of which corresponds to a spectral image. Each object estimate is iteratively adjusted applying a system spectral optical transfer function (“SOTF”) to it and modifying it until a match is made with the corresponding spectral image. Each adjusted object estimate is then iteratively restored by applying a system optical transfer function (“OTF”) to it and then applying a DC bias to it until a match is made between the identified region in the sum of the object estimates and the identified region of a measured panchromatic object image.

Abstract: A spectrophotometer incorporating an interferometer and a dispersive system is adapted to have an enlarged inlet field without degrading its spatial resolution. To this end, spectral data deduced horn measurements performed by means of the interferometer are transferred into spectral data deduced from measurements per formed by means of the dispersive system. Such spectrophotometer makes it possible to scan an observation field quickly, and is compatible with use on board a satellite.

Abstract: An apparatus and method are provided. In particular, at least one first electro-magnetic radiation may be provided to a sample and at least one second electro-magnetic radiation can be provided to a non-reflective reference. A frequency of the first and/or second radiations varies over time. An interference is detected between at least one third radiation associated with the first radiation and at least one fourth radiation associated with the second radiation. Alternatively, the first electro-magnetic radiation and/or second electro-magnetic radiation have a spectrum which changes over time. The spectrum may contain multiple frequencies at a particular time. In addition, it is possible to detect the interference signal between the third radiation and the fourth radiation in a first polarization state. Further, it may be preferable to detect a further interference signal between the third and fourth radiations in a second polarization state which is different from the first polarization state. The first and/or second electro-magnetic radiations may have a spectrum whose mean frequency changes substantially continuously over time at a tuning speed that is greater than 100 Tera Hertz per millisecond.

Abstract: A Fourier transform spectrometer based on a modified Sagnac interferometer is described. The instrument uses one or more gratings as dispersive elements to greatly improve the spectral resolution, and in-line optics to match the beam size in the interferometer to optimize the efficiency. The resolution can approach about 0.6 GHz at about 632.8 nm (λ/Δλ=8.4×105). A CCD or photodiode array is used as the detector and the fast Fourier transform of the fringe pattern is performed by a computer. Some embodiments employ no mechanically moving parts; therefore, they are compact and easy to align. Practical applications include remote sensing, process monitoring, and basic research. The fast response time of the detector also allows real time spectral analysis.
