    Abstract: The present invention relates to a method and system for fiber positioning in wide-field astronomy. In one form the method and system of the present invention relate to anchoring fiber end points adjacent or against the field plate of a telescope. In one embodiment the positioning system for anchoring a fiber end point at a location on a telescope field plate collocated with a telescope focal plane, the positioning system comprising a piezoelectric positioning device for positioning the fiber end point, the positioning device comprising a chamber having an opening, the opening lying against the field plate in use defining a substantially enclosed volume inside the chamber, a pump for reducing pressure inside the enclosed volume; and a path connecting the pump and the enclosed volume so that, in use, the pump effects a reduction in pressure in the chamber thereby anchoring the fiber end point on the field plate.

    Abstract: Computed tomography imaging spectrometers (“CTIS”s) having color focal plane array detectors are provided. The color FPA detector may comprise a digital color camera including a digital image sensor, such as a Foveon X3® digital image sensor or a Bayer color filter mosaic. In another embodiment, the CTIS includes a pattern imposed either directly on the object scene being imaged or at the field stop aperture. The use of a color FPA detector and the pattern improves the accuracy of the captured spatial and spectral information.

    Abstract: To achieve a given spectral resolution with reduced detector size and commercially available pixel pitches, the Raman spectrum is shifted across the detector array such as by one of the following methods: 1) tuning the excitation wavelength; 2) rotating the grating; 3) displacing the effective input slit (fiber) and acquiring the spectrum under stepped displacement conditions; and 4) displacement of a lens relative to input fiber to displace effective input slit relative to the detector. A composite spectrum is formed and deconvolution of the entrance aperture image and/or pixel masking is then used.
