  • Patent number: 10616461
    Abstract: Aspects and examples are generally directed to broadband optical systems and methods for collecting a wide spectral range of electromagnetic radiation with a single window optical assembly. In one example, a broadband optical system includes a segmented window positioned to receive electromagnetic radiation, the segmented window including at least a first segment formed from a first material and a second segment formed from a second material, the first segment being configured to transmit a first spectral band of the electromagnetic radiation along an optical path and the second segment being configured to transmit a second spectral band of the electromagnetic radiation along the optical path. The broadband optical system may include an optical de-multiplexer configured to spatially separate the first and second spectral bands, and foreoptics interposed between the segmented window and the optical de-multiplexer to direct the electromagnetic radiation from the segmented window to the optical de-multiplexer.

  • Patent number: 9857223
    Abstract: An interferometer system comprising an optical detector including a substrate and a two-dimensional array of pixels disposed on the substrate is provided. The interferometer system may further comprise an interferometer disposed proximate the optical detector without an optical element between the interferometer and the optical detector. The interferometer may include a first plate positioned proximate the substrate and extending over the two-dimensional array of pixels, a second plate spaced apart from the first plate, the first and second plates defining an optical gap between them, and at least one actuatable spacer positioned between the first plate and the second plate and configured to space apart the first and second plates from one another and to selectively alter a thickness of the optical gap.

  • Patent number: 8861106
    Abstract: Systems for generating uniform monochromatic electromagnetic radiation that include an electromagnetic radiation source and a bandpass filter assembly to filter electromagnetic radiation emitted by the electromagnetic radiation source. The systems also include an optical integrating sphere to receive the filtered electromagnetic radiation and to uniformly scatter the filtered electromagnetic radiation within the optical integrating sphere, wherein the optical integrating sphere comprises an output to emit the uniformly scattered, filtered electromagnetic radiation.

  • Patent number: 5793034
    Abstract: A laser-based target detection system applicable for search-and-rescue type operations takes into account a plurality of optical attributes in the energy delivered to, and received from, a target-containing area so as to enhance effectiveness. In addition to analyzing the returned optical signature for sufficient energy reflected by a potential target at a primary laser wavelength, the system also senses the target's effect on a supplemental optical attribute, and only when sufficient amplitude at the primary wavelength is detected in conjunction with a substantial effect on the supplemental optical attribute is a valid target confirmed. In one embodiment, the supplemental optical attribute is amplitude at a wavelength other than the primary wavelength, with the system preferably looking for a high degree of attenuation at the non-primary wavelength.
