Abstract: A system for simultaneously producing multiple images substantially identical images on multiple separate detector planes is disclosed. A reflective spatially beam-splitting element preferably comprising multiple reflective areas is preferably placed at a location substantially coincident with the pupil or aperture of the system. In non-diffraction limited systems, each area preferably comprises an actual cross section that is circular or has the rotational symmetry (or a multiple thereof) of the number of images to be formed. In diffraction limited systems, all of the areas preferably comprise actual cross sections that have the same shape, size and orientation with respect to the incoming optical beam. Each individual actual cross section may be due to the shape of each area, optionally in combination with a mask. Appropriate selection of filters enables real-time multi-spectral scientific imaging, imaging polarimetry, or high dynamic range imaging (HDRI) for photography and cinematography, even with a moving camera and/or moving subjects.

Abstract: Multimodal/multispectral images of a population of cells are simultaneously collected. Photometric and/or morphometric features identifiable in the images are used to separate the population of cells into a plurality of subpopulations. Where the population of cells includes diseased cells and healthy cells, the images can be separated into a healthy subpopulation, and a diseased subpopulation. Where the population of cells does not include diseased cells, one or more ratios of different cell types in patients not having a disease condition can be compared to the corresponding ratios in patients having the disease condition, enabling the disease condition to be detected. For example, blood cells can be separated into different types based on their images, and an increase in the number of lymphocytes, a phenomenon associated with chronic lymphocytic leukemia, can readily be detected.

Abstract: Methods and apparatus enable compensation of source light wavelength fluctuations due to instability of a broadband source within an optical sensing system. Tapping off two or more portions of the light output from the source at specific wavelength bands enables power based measurements of these portions. The measurements provide compensation ability by either use as feedback to control the source or for determination of the central wavelength so that adjustments can be applied to sensor response signals received at a receiver.

Abstract: In a method and apparatus for detecting optical spectra, two or more partial beams are generated from an incident beam, each of said partial beams being assigned to a different spectral region. The partial beams travel through a spectrometer lens system and are detected in a spatially separated manner. For this purposes, the partial beams generated from the incident beam are directed to respective spatially separated diffraction gratings that are virtually superimposed in the beam path, and are assigned to different spectral regions. After passing through the diffraction gratings, the spectrally separated partial beams are combined to a joint beam path traveling through the spectrometer lens system. Preferably, the partial beams comprising the different spectral regions can be spectrally separated after passing through the spectrometer lens system and can be detected in spatially separated detectors assigned to the different spectral regions.

Abstract: A sensor system for remote object detection, tracking, characterization, and discrimination can have a plurality of sensors. A shared optical train that can facilitate blending of information from the sensors, so as to provide a single view for the plurality of sensors. Small and/or dim objects can be more readily detected. High-resolution 3 dimensional space object imagery and on-demand target information gathering can be provided with reduced data latency. The undesirable effects of atmospheric turbulence along the aiming direction can be mitigated even when there is a high relative velocity between the surveillance platform and remote target.
