Abstract: A situation awareness sensor includes a plurality of N sensor channels, each channel including an optical phased array (OPA) having a plurality of solid-state laser emitters, a command circuit and a detector. The command circuit controls the relative phase between the laser emitters to command a divergence, shape and exit angle of a spot-beam to scan a channel field-of-view (FOV). The OPAs may be controlled individually or in combination to command one or more spot-beams to scan an aggregate sensor FOV and to track one or more objects.

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 translation: 基于多光束三角测量的测距仪可以将多个光束从不同的方向引导到样品上。 测距仪可以使用象限检测器来检测来自样品反射的多个光束的光。 当目标距离测距仪的指定距离时,测距仪产生一个触发信号。 在一些示例中,多个波束中的两个或更多个同时被引导到样本上,其中波束以不同的频率被调制,并且来自象限检测器的信号以相应的频率被分析。 在一些示例中,多个光束中的两个或更多个被连续地引导到样本上,其中来自象限检测器的信号在相应的时间窗口中被分析。 与象限检测器一起使用多个光束可以提高针对样品相对于测距仪的相对倾斜的鲁棒性。

Abstract: An image polarimeter includes a MEMS MMA divided into two or more segments in which the mirrors in each segment are provided with a polarizer of a given polarization. The mirrors in each segment are tipped and tilted to steer polarized light onto different portions of an optical detector. In certain configurations the mirrors may also be pistoned to reduce aberrations. Each frame that is read out from the detector includes two or more distinct component polarized images having different polarizations P0, P2, . . . of the same scene to fully characterize the polarization properties of the scene. Since the mirrors only tip/tilt/piston in the dead period between frames, no components are moving during image acquisition and co-registration of the component polarized images is simple. The number of segments and the different polarizations may be selected to implement Jones calculus, Mueller calculus and Stokes parameters or other polarimetry techniques.
