Abstract: The spectrometer comprises a radiation source (1) whose radiation is focused on an entrance slit (5) of an echelle monochromator (6, 7, 8, 9, 10). A fibre optic bundle (52) has one end (51) located above a slot on the output plate (10) of the echelle monochromator and its other end (53) located adjacent an array detector (54). The fibre optic bundle (52) has a card (59) attached to it which specifies the respective positions of the ends of each fibre within the bundle. A card reader (58) reads this information and passes it to a memory (61). A microprocessor (57) is used to relate the outputs of a given detector element to a given wavelength of radiation using the information read from the card (59).

Abstract: The application of one or more multifunctional holographic optical elements (HOE's) (40, 16) to a photometric apparatus, and a spectrophotometer in particular, is disclosed. Fabrication methods for HOE's especially useful in the foregoing application result in holograms which perform several classical optical (i. e., light gathering and steering) functions. The HOE's so fabricated are useful in a detector mode (16) (i.e., to process light from an illuminated sample for analysis of some portion of its spectrum); in a source mode (40) (i.e., processing light from a source (51) to a focus on a sample); and a combination of source and detector modes.

Abstract: A video pixel spectrometer system employs an image aquisition device (12) and a spectrometer (14) to provide a video display of the spectral characteristics of an image sector for a series of discrete positions of the image sector. The output from the spectrometer (14) is converted to digital data and processed for displaying various video displays (D1, D2, D3, D4 and D5) of the spectral characteristics. Cameras (24, 26 and 28) are also employed to acquire images for processing of various physical features and to aid in positioning the input image.
