Abstract: A multispectral imaging system and method in which the zero-mode channel is used to provide imaging of any of a variety of optical properties. In one example an imaging method includes spectrally dispersing received electromagnetic radiation into its spectral components with a dispersive element to produce spectrally dispersed electromagnetic radiation, transmitting the electromagnetic radiation through the dispersive element to produce non-dispersed electromagnetic radiation corresponding to a zero order diffraction mode of the dispersive element, imaging the non-dispersed electromagnetic radiation to produce a zero-mode image, and simultaneously imaging the spectrally dispersed electromagnetic radiation to produce a spectral image.

Abstract: A solid monolithic spectrograph utilizes the Czerny-Turner geometric confration. It has a base constructed of BK7 optical glass to which all components are affixed with optical epoxy. The compact spectrograph operates in the visible spectrum in second order thereby permitting it to be smaller by a factor of two than if it operated in first order. The spectrograph is programmable and is capable of simultaneous multi-channel measurements of wavelengths and bandwidths of sources in the visible and near infrared spectral regions.

Abstract: A method includes receiving collimated light from an optical imaging system and dividing the received light into multiple bands of wavelength. Each band is refocused onto a corresponding diffraction grating having an amplitude function matched to a point spread function (PSF) of the optical imaging system. The light that is not filtered out by the diffraction grating is transmitted onto a corresponding pixel array. An image is reconstructed from data provided by the pixel arrays for each band. The intensity of light scattered by each diffraction grating may be detected, with the image being reconstructed as a function of an average value of detected intensity of scattered light used to scale the known zero-order mode profile, which is added to the image on the pixel array.
