  • Patent number: 10198790
    Abstract: Described in this disclosure is a space-variant Multi-domain Foveated Compressive Sensing (MFCS) system for adaptive imaging with variable resolution in spatial, polarization, and spectral domains simultaneously and with very low latency between multiple adaptable regions of interest (ROIs) across the field of view (FOV). The MFCS system combines space-variant foveated compressive sensing (FCS) imaging covered by a previous disclosure with a unique dual-path high efficiency optical architecture for parallel multi-domain compressive sensing (CS) processing. A single programmable Digital Micromirror Device (DMD) micro-mirror array is used at the input aperture to adaptively define and vary the resolution of multiple variable-sized ROIs across the FOV, encode the light for CS reconstruction, and adaptively divide the input light among multiple optical paths using complementary measurement codes, which can then be reconstructed as desired.

  • Patent number: 10128399
    Abstract: A lateral-effect position-sensing detector includes a second lateral-current collector layer, an electron barrier layer on the second lateral-current collector layer, an absorber layer on the electron barrier layer, a first lateral-current collector layer on the absorber layer, and a first elongate electrical contact and a second elongate electrical contact on each of the lateral-current collector layers. Incident light radiates a transparent first lateral-current collector layer to be absorbed by the undepleted absorber layer where electron and holes are generated. The depleted electron barrier layer prevents a flow of electrons from the absorber layer to the second lateral-current collector layer but allows electrons to flow to the second lateral-current collector layer. The lateral-effect position-sensing detector is sensitive to a lateral position between the first elongate electrical contact and the second elongate electrical contact of incident light on each of the lateral-current collector layer.

  • Patent number: 10050704
    Abstract: Several embodiments of a system and method of an optical-frequency (OF) synthesizer are disclosed that produces an optical frequency (OF) tone derived from a dispersive resonator and phase-locking to a radio frequency (RF) tone to achieve high precision. Thus, the stability of the synthesized OF tone is related to the stability of the RF tone. A frequency control word provides for a wide range of programmability to the frequency of the output OF tone. The OF synthesizer establishes the absolute value of the optical frequency of its output tone by making use of a dispersive optical resonator and applying appropriate corrections obtained dynamically by interrogating the comb lines. The reference resonator defines a semi-dormant OF reference comb, wherein the lines of that reference comb are associated with the modes of the reference resonator. Several selected modes of this reference resonator are interrogated by locking the frequency of light emitted by lasers to those resonator modes.

  • Patent number: 10020331
    Abstract: Systems and methods for a multi-band position sensor and a multi-band optical detector are disclosed. This system comprises a dual-axis, lateral-effect position sensor for locating spots of light that has energy in two wavelength bands. This sensor senses the time-varying intensities of the light in each of the two wavelength bands. This sensor also provides the location of the spot of light on the light-detecting plane of the sensor. Examples are provided for light of two mid-wave infrared (MWIR) wavelength bands or of a short-wave infrared (SWIR) and a MWIR band. This sensor approach, could be applied to detect light of other wavelength bands, such as a combination of a MWIR and a long-wave infrared (LWIR) band. This concept is extended to an array of detectors for multi-band optical detection and multi-source location and tracking. Monolithic chip level fabrication of the multi-band detectors is also discussed.
