A system for generating reflectance values for a target that includes a plurality of electromagnetic radiation sources for irradiating the target, an imager for generating a plurality of digital representations of the target that includes an array of filter elements for filtering electromagnetic radiation reflected by the target through an array of filter elements, and a detector for detecting the filtered electromagnetic radiation at an array of detection elements. The system includes processors for determining a set of reflectance values for a portion of the target based on a first digital representation of the target generated in response to irradiation of the target with radiation of a first wavelength band and a second digital representation of the target generated in response to irradiation of the target with radiation of a second wavelength band.

Active hyperspectral imaging system

A method of optical spectroscopy and a device for use in optical spectroscopy. The device includes a substrate, and a plurality of etalon cavities affixed to or coupled to the substrate. A signal is received from a Fabry-Perot interferometer. The signal is sampled using the device according to a generalized Nyquist-Shannon sampling criterion. The signal is sampled using the device according to a phase differential criterion for wave number resolution. An input spectrum for the signal is reconstructed based on the signal sampled according to the generalized Nyquist-Shannon sampling criterion and the signal sampled according to the phase differential criterion for wave number resolution.

A computer implemented method is provided for computing a two-way optical flow between a reference frame and one or more associated frames in an optical flow module. A forward warping operator and a backward warping operator can be generated between the reference frame and each of the one or more associated frames in a warping module. The forward warping operator and the backward warping operator provide motion compensation between the frames. Weights for each of the forward warping operators and the backward warping operators can be computed in a weight module. The weights correspond to uncertainty of motion estimation. A super resolution iteration algorithm can be calculated in a super-resolution iteration module.
