Abstract: Aspects and embodiments are generally directed to active imaging systems and methods. In one example, an active imaging system includes a positioning system configured to detect a direction of motion of the imaging system relative to a scene, an optical source positioned to emit electromagnetic radiation, a non-mechanical beamsteering device positioned to receive the electromagnetic radiation from the optical source and configured to scan the electromagnetic radiation over at least a first portion of the scene within an instantaneous field-of-view of an optical receiver, and the optical receiver positioned to receive reflections of the electromagnetic radiation from at least the first portion of the scene within the instantaneous field-of-view, wherein the first portion of the scene is within a first edge region of the instantaneous field-of-view of the optical receiver, the first edge region being in the direction of motion of the imaging system.

Abstract: A ring amplifier amplifies one or more spot-beams that scan a circular pattern in a two-dimensional FOV to extend the range of range steerable laser transmitter or an active situational sensor. Mechanical, solid-state or optical phase array techniques may be used to scan the spot-beam(s) in the circular pattern. Mirrors are preferably positioned to redirect the spot-beams to enter and exit the ring amplifier through sidewalls to amplify the spot-beam and return it along a path to scan the circular pattern. For efficiency, the pumps and thermal control may be synchronized to the circular scan pattern to only pump and cool the section of gain medium in which the spot-beam is currently scanned and the next section of gain medium in the circular scan pattern.

Abstract: A system for providing active refraction feedback for devices with a variable index of refraction includes a reference beam generator and an altered reference beam sensor. The reference beam generator is configured to generate a reference beam and to apply the reference beam to a variable-index-of-refraction (VIR) device. The VIR device is configured to generate an altered reference beam based on the reference beam and based on an index of refraction for the VIR device. The altered reference beam sensor is configured to detect the altered reference beam and to sense a characteristic of the altered reference beam corresponding to the index of refraction.

Abstract: A multiple-beam triangulation-based range finder can direct multiple beams onto a sample from different orientations. The range finder can use a quadrant detector to detect light from the multiple beams that is reflected from the sample. The range finder generates a trigger signal when the target is a specified distance from the range finder. In some examples, two or more of the multiple beams are directed onto the sample simultaneously, where the beams are modulated at different frequencies and the signals from the quadrant detector are analyzed at the respective frequencies. In some examples, two or more of the multiple beams are directed onto the sample in succession, where the signals from the quadrant detector are analyzed in respective time windows. Using multiple beams with the quadrant detector can increase robustness against relative tilt of the sample with respect to the range finder.

Abstract: The design of an existing air-to-air missile seeker is adapted to new missions that require both active laser illumination and detection (passive or active) capabilities. The gimbal is used to point the laser beam to a desired location in a transmit FOR. This approach minimizes the size, weight and power of the sensor because only a small portion of the transmit FOR is illuminated at any instant. This minimizes the laser output required, which reduces the power to operate the laser and the power to maintain the laser at operating temperature. In existing seekers, the gimbal points the detector in the desired direction to expand its FOR. To address the limitations of coupling the laser beam into the gimbaled optical system, the gimbal cannot perform the steering function for the detector. Instead, a staring detector receives light through an off-gimbal aperture within a fixed receive FOR that overlaps the transmit FOR.

Abstract: An obstacle detector uses a Micro-Electro-Mechanical System (MEMS) Micro-mirror Array (MMA) for scanning one or more laser beams over a field of regard to identify negative obstacles in the path of an autonomous vehicle or in other limited visual environments. In certain examples, the MEMS MMA may be segmented to concurrently and independently form and scan multiple laser beams over the field of regard to interrogate different areas, concurrently identify and verify candidate objects, maintain specified spatial resolution or implement a composite scan pattern. The MEMS MMA may be configured to concurrently and independently scan multiple laser beams at different wavelengths or spectral bands. The MEMS MMA may be configured to adjust a size, divergence or intensity profile of the laser beam(s) or to provide wavefront correction to compensate for atmospheric distortion. In certain embodiments, the MEMS MMA may be provided with tip, tilt and piston actuation of the mirrors to form the laser beams.

Abstract: A warning receiver can be detachably mounted on the inside of a window of a manned platform to detect RF or RF and laser threats and to provide visual or audio warnings to the human occupant. The warning receiver is fully self-contained and independent of any systems on the manned platform. In different packaging configurations, the receiver can be manually rotated to better visualize the threat and/or the receiver's human-machine interface (HMIF) can be manually rotated to better display the warnings. Although most typically used in manned aircraft the warning receiver can be used in other manned vehicles or ships.

Abstract: Optical sensors and particularly gimbaled optical sensors transmit an active signal at a given wavelength(s) and receive passive signals over a range of wavelengths and the active signal in a common aperture. The sensor includes a Tx/Rx Aperture Sharing Element (ASE) configured with a center region that couples the active signal to the telescope for transmission and an annular region that couples the passive emissions and the returned active signal to the detector. A filter wheel may be positioned behind the ASE to present separate passive and active images to the detector. These optical sensors may, for example, be used with guided munitions or autonomous vehicles.
