  • Publication number: 20210297161
    Abstract: An RF imaging receiver using photonic spatial beam processing is provided with an optical beam steerer that acts on the individual modulated optical signals to induce individual phase delays that produce a phase delay with a linear term, and possibly spherical or aspherical terms, across a two-dimensional wavefront of the composite optical signal to steer the composite optical signal and move the location of the spot on the optical detector array. The optical beam steerer may change the path length or a refractive index for each of the modulated optical signals to induce the requisite phase delays. The optical beam steerer may be implemented, for example, with a Risley prism or liquid crystal or MEMs spatial light modulator.

  • Publication number: 20210296770
    Abstract: An RF imaging receiver using photonic spatial beam processing focuses a composite optical signal into a spot on an optical detector array to extract an image of an RF scene. The receiver steers the composite optical signal to move the location of the spot to increase the detected power in the image and selectively turns off one or more detector pixels around the spot to reduce noise in the image.

  • Patent number: 11127150
    Abstract: A multiple target tracker and beam steerer utilizes a micro-electro-mechanical system (MEMS) micro-mirror array to illuminate multiple tracked targets per frame one target at a time for designation, range finding or active imaging. The steering rate and range afforded by the MEMS micro-mirror array supports various tracker configurations (out-of-band, in-band or dual-band video cameras), LADAR detectors (single pixel or pixelated) and prioritization of tracked targets to vary the revisit rate or dwell time for an illuminated target. A user interface accepts commands from an operator to select the targeting mode, control cue-box size and position within the FOV and target selection. The MEMS micro-mirror array may be used to reflect beams and/or optical signals, in some embodiments.

  • Publication number: 20210231413
    Abstract: A DE energy weapon and tracking system includes a passive millimeter wave (PmmW) imaging receiver on a common gimbaled telescope to sense natural electromagnetic radiation from a mmW scene. The PmmW imaging receiver operates in a portion of the electromagnetic spectrum distinct from the IR bands associated with thermal blooming or the HEL laser. In the case of a HPM source, the reflected energy is either in a different RF band and/or of diminished amplitude such as to not interfere with operation of the PmmW imaging receiver. Although lower resolution than traditional optical imaging, PmmW imaging provides a viable alternative for target tracking when the DE weapon is actively prosecuting the target and provides additional tracking information when the DE weapon is not engaged.

  • Publication number: 20210092260
    Abstract: An active mode image sensor for optical non-uniformity correction (NUC) of an active mode sensor uses a Micro-Electro-Mechanical System (MEMS) Micro-Mirror Array (MMA) having tilt, tip and piston mirror actuation to form and scan a laser spot that simultaneously performs the NUC and illuminates the scene so that the laser illumination is inversely proportional to the response of the imager at the scan position. The MEMS MMA also supports forming and scanning multiple laser spots to simultaneously interrogate the scene at the same or different wavelengths. The piston function can also be used to provide wavefront correction. The MEMS MMA may be configured to generate a plurality of fixed laser spots to perform an instantaneous NUC.

  • Patent number: 10866487
    Abstract: A monolithically integrated wavelength converted photonic integrated circuit (PIC) is fabricated by forming a trench in the PIC's insulating layer to expose a portion of an output waveguide that transmits a photonically processed optical signal at frequency ?1. A non-linear waveguide formed of a non-linear material with non-linear susceptibility at frequency ?1 and a transmission bandwidth spanning both ?1 and m*?1 where m is an integer of at least two is fabricated in direct physical contact with the exposed portion of the output waveguide. A patterned structure is fabricated in or on the non-linear waveguide to enhance non-linear susceptibility to generate an optical signal at frequency m*?1, which may be emitted directly or coupled to an optical antenna.
