Abstract: A spectrometer (20) has a source of illumination radiation (21) having a plurality of spectral wavelengths, a bandpass filter (14), a dispersive beamsplitter (28), an illumination radiation rejection filter (34), and a spectrograph (32) each tunable in correspondences to a selected one of the plurality of spectral wavelengths of the source of illumination radiation. Any one of the tunable elements can comprise a holographic volume dispersion distraction grating and a mirror, both having fixed orientation displacement with respect to each other and being rotable for tuning around an avis corresponding to the interaction of the two planes coincident with the surfaces of said mirror and said grating.

Abstract: A multi-spectrum, multi-channel imaging spectrometer includes two or more input slits or other input for each input channel. The input slits are vertically and horizontally displaced from each other. The vertical displacements cause spectra from the channels to be vertically displaced on a single image sensor on a stationary image plane. The horizontal displacements cause light beams from the input channels to strike a convex grating at different incidence angles and produce separate spectra having different spectral ranges. A retroflective spectrometer includes a convex grating that, by diffraction, disperses wavelengths of light at different angles and orders approximately back along an incident light beam. A single concave mirror reflects both the input channel and the dispersed spectrum. A prism, set of mirrors, beam splitters or other optical element(s) folds the input channel(s) of a spectrometer to enable the input(s) to be moved away from the plan of the image sensor.

Abstract: An individualized modeling equation for predicting a patient's blood glucose values is generated as a function of non-invasive spectral scans of a body part and an analysis of blood samples from the patient, and is stored on a central computer. The central computer predicts a blood glucose value for the patient as a function of the individualized modeling equation and a non-invasive spectral scan generated by a remote spectral device. If the spectral scan falls within the range of the modeling equation, the predicted blood glucose level is output to the patient. If the spectral scan falls outside the range of the modeling equation, regeneration of the model is required, and the patient takes a number of noninvasive scans and an invasive blood glucose level determination. The computer regenerates the individualized modeling equation as a function of the set of spectral scans and corresponding blood glucose values.
