    Abstract: A method for measuring a property of radiation from different sources such as moving particles or different spatial locations on each particle includes providing a spatial modulator common to all of the sources having a sequence of configurations, each of which configurations causes the radiation flux to pass along paths to respective modulation ports and cycling the common spatial modulator past each of the modulation ports so that the sequence of configurations is applied to each modulation port. The sequence of configurations comprises an ordered array of optical elements on a substrate. In one embodiment, the modulator is arranged in a circle around an axis of rotation of a rotating singulation disk. At least one source is a reference source which has not interacted with the source to be analyzed and the sample and reference sources are compared.

    Abstract: A system and method are provided for spectral imaging an object or scene 2. A first image 2a of the object or scene 2 is projected on a spatial modulator 6 and divided into a plurality of first image segments 2a′ modulated with a respective plurality of modulation frequencies f1-fN. A spectrally resolved second image segment 2b′ of each first image segment 2a′ is projected onto a sensor 4 forming a second image 2b in such a way that overlapping spectral components λ of different second image segments 2b′ on the sensor 4 originating from different first image segments 2a′ have distinct modulation frequencies f1-fN. The projected second image segments 2b′ are read out from the sensor 4 and demodulated according to the distinct modulation frequencies f1-fN. In this way projected second image segments 2b′ overlapping on the sensor 4 may be distinguished on the basis of the distinct modulation frequencies f1-fN.

    Abstract: Optically diverse coded aperture imaging (CAI) includes imaging a scene which is multi-spectrally diverse or polarimetrically diverse. A CAI system allows light rays from a scene to pass to a detector array through a coded aperture mask within an optical stop. The mask has multiple apertures, and produces overlapping coded images of the scene on the detector array. Detector array pixels receive and sum intensity contributions from each coded image. The detector array provides output data for processing to reconstruct an image. The mask provides for multi-spectral information to become encoded in the data. A linear integral equation incorporating explicit wavelength dependence relates the imaged scene to the data. This equation is solved by Landweber iteration to derive a multi-spectral image. An image with multiple polarisation states (polarimetric diversity) may be derived similarly with a linear integral equation incorporating explicit polarisation dependence.

    Abstract: A spectral encoder for producing spectrally selected images of a radiation field containing multiple spectral components. An imaging spectrograph defines a first optical path that produces from the input radiation field a spectrally dispersed image comprising multiple spectral components displaced along a dispersion direction. Spectral pass bands are encoded on the dispersed image by a programmable spatial light modulator using one or more spatial masks. The imaging spectrograph further defines a second optical path that reverses the spectral dispersion of the first path and produces a spectrally-encoded polychromatic output image containing only those spectral components encoded by the spatial mask. The first and second optical paths share a common dispersing element. A detector records at least one spatial region of the spectrally encoded output image.
