摘要： The present application discloses a system comprising a compact curved grating (CCG) and its associated compact curved grating spectrometer (COGS) or compact curved grating wavelength multiplexer/demultiplexer (WMDM) module and a method for making the same. The system is capable of achieving a very small (resolution vs. size) RS factor. The location of the entrance slit and detector can be adjusted in order to have the best performance for a particular design goal. The initial groove spacing is calculated using a prescribed formula dependent on operation wavelength. The location of the grooves is calculated based on two conditions. The first one being that the path-difference between adjacent grooves should be an integral multiple of the wavelength in the medium to achieve aberration-free grating focusing at the detector or a first anchor output slit even with large beam diffraction angle from the entrance slit or input slit, the second one being specific for a particular design goal of a curved-grating spectrometer.

摘要： A novel dispersion optical system based on at least one grating is provided. The pitches of the grating are linearly modulated so that the incident light is dispersed into different monochromatic light at different diffraction angles. In such a system, an order sorting filter is not required to separate the light of a selected order from the rest of unwanted overlapped order.

摘要： A spectrometer includes a pair of crossed reflective gratings to effect a spectrally dispersed beam that is focussed to an array detector. The second grating is a plural grating with a surface formed of a first portion and a second portion. The first portion has a groove density for effecting ultraviolet in the dispersed beam. The second portion has a groove density for effecting visible radiation in the dispersed beam. A shutter blocks or exposes the second portion of the grating surface so as to select the first spectral range or the second spectral range for detection. The plural grating surface preferably may be contoured to compensate for aberrations in focussing of the beam to the detector. A computer may be used for selecting spectral lines for analysis, particularly selecting such lines in the second range that are not interfered with by the first range.

A polychromat is employed to combine a plurality of beams, each derived from a separate source, into a single output beam, thereby providing for definition of one or more of the intensity, color, color uniformity, divergence angle, degree of collimation, polarization, focus, or beam waist of the output beam. The combination of sources and polychromat may serve as an enhanced-privacy display and to multiplex signals of multiple spectral components.
