    Abstract: According to one aspect, a multi-heterodyne system is disclosed, which comprises a first laser source for generating multi-mode radiation having a frequency spectrum characterized by a first plurality of phase coherent frequencies, and a second laser source for generating multi-mode radiation having a frequency spectrum characterized by a second plurality of phase coherent frequencies. The system further comprises at least one detector for detecting a combination of the multi-mode radiation generated by the first and second laser sources so as to provide a multi-heterodyne signal having a frequency spectrum characterized by a plurality of beat frequencies, each beat frequency corresponding to a pairwise difference in the first and second plurality of phase coherent frequencies. The system further comprises an analyzer for receiving said multi-heterodyne signal and configured to employ a predictive model of the multi-heterodyne signal to provide estimates of any of phase error and timing error associated with the beat frequencies.

    Abstract: An apparatus for measuring a wavelength-dependent optical characteristic of an optical system has a light-pattern generation device which generates a pattern of polychromatic light in an object plane. Together with the optical system, a measuring optical unit images the object plane on a spatially resolving light sensor. A dispersive optical element is arranged in a light path between the optical system and the light sensor in such a way that a plurality of images of the pattern with different wavelengths are generated simultaneously on the light sensor. The evaluation device determines the wavelength-dependent characteristic of the optical system from the plurality of images on the light sensor.

    Abstract: An apparatus for simultaneously measuring linear and circular polarization components of light is provided, and contains no moving parts. The apparatus may include a prism assembly configured to receive collimated light and splits the light into different directions according to its polarization state. The apparatus may also include lenses configured to collimate light from an image plane to be analyzed by the prism assembly, or direct the light that is split by the prism assembly to different detectors or locations on an image plane.

    Abstract: A multi-spectral photon converting imaging apparatus and method are disclosed. A plurality of photons in a first received band and a plurality of photons in a second received band are received by a first nanoparticle photon conversion material. The first nanoparticle photon conversion material converts the plurality of photons in the first received band to a plurality of photons in a first converted band, and the plurality of photons in the second received band to a plurality of photons in a second converted band. An image sensor receives the plurality of photons in the first converted band and the plurality of photons in the second converted band, and generates a digitized image of the scene based on the plurality of photons in the first converted band and the plurality of photons in the second converted band.
