Abstract: A Sagnac interferometer can include a beamsplitter arranged to receive an input beam of light of a design wavelength, to split the input beam of light into first and second beams that counter propagate around an optical path, and to recombine the first and second beams into an output beam of light. The optical path can include at least one diffraction grating that is arranged to satisfy an effective Littrow geometry.

Abstract: The present invention discloses apparatuses and methods for non-invasive determination of attributes of human tissue by quantitative infrared spectroscopy. The embodiments of the present invention include subsystems optimized to contend with the complexities of the tissue measurements. The subsystems can include an illumination/modulation subsystem, a tissue sampling subsystem, a calibration maintenance subsystem, a data acquisition subsystem, and a computing subsystem. Embodiments of the present invention provide analyte property determination and identity determination or verification from the same spectroscopic information, making unauthorized use or misleading results less likely that in systems that include separate analyte and identity determinations. The invention can be used to prevent operation of automobiles or other equipment unless the operator has an acceptable alcohol concentration, and to limit operation of automobiles or other equipment to authorized individuals who are not intoxicated or drug-impaired.

Abstract: The invention relates to a method of obtaining stigmatic imaging in spectral analysis using a concave grating in offplane mounts. The invention comprises placing on one hand the object, which may be an entrance slit, and on the other the focal surface in such a manner with respect to the concave grating that certain conditions specified in disclosed formulae and relating to an othogonal three dimensional coordinate system the origo of which lies in the middle of the grating surface, the X-axis of which runs along the normal to the grating surface, and the Z-axis of which is parallel with the grooves of the grating, are satisfied at a value for the angle between the XY-plane and a line from a selected point on the object to origo that differs from zero.

Abstract: The grating of an asymmetric, double pass, grating monochromator has an axis of rotation which extends at an angle Psi relative to a normal to a plane H H''. That plane is normal to, and bisects, a line extending between the monochromator entrance and exit slits. The angle Psi is characterized in that spectral overlap is substantially elmininated.
