    Abstract: A linear frequency domain grating and a multiband spectrometer having the same. The linear frequency domain grating includes a dispersive optical element and a diffractive optical element being substantially in contact with the dispersive optical element or being substantially integrated with the dispersive optical element, configured to receive a beam of incident light along an incident optical path, and diffract and disperse it into its constituent spectrum of frequencies of the light that is output from the dispersive optical element along an output optical path, such that the output light has a spatial distribution on a focal plane in the output optical path that is a linear function of the frequency. The linear frequency domain grating is a transmissive-type grating or a reflective-type grating, depending on whether the incident optical path and the output optical path are in different sides or the same side of the diffractive optical element.

    Abstract: A noninvasive analyzer apparatus and method of use thereof is described for spatially separating light having noninvasively probed a tissue volume into groups, which narrows standard deviations of probed tissue pathlength for each of the groups. Reduction in tissue pathlength uncertainty subsequently enhances noninvasive analyte concentration determination accuracy. Control of individual detector distance from an illumination zone in combination with control of area of a detection zone coupled to an individual detector yields intensity control of the various groups. The intensity control is optionally aided using several intensity control elements including: control of detector response shape, hardware gain settings set as function of distance from the illumination zone, varying numerical aperture of light collection optics as a function of position from the illumination zone, multiple illumination-detector linked bundlets, micro-optics, segmented spacers, arcs of detector elements, and/or outlier analysis based on detected intensity as a function of position.
