Abstract: A method includes forming an image of a scene on a sensor through a coded aperture, wherein the coded aperture and sensor are optically coupled within an imaging platform to form a superpositioned, physically encoded image of the scene on the sensor. The method includes generating raw image data from the sensor representative of the superpositioned, physically encoded image of the scene, and transmitting the raw image data to a platform remote from the imaging platform so the raw data is encrypted during transmission. The method can include using the platform remote from the imaging platform to deconvolve the superpositioned, physically encoded image into a decoded image.

Abstract: A method includes forming a first image of a scene through a static coded aperture onto a sensor with the static coded aperture in a first position relative to the sensor, shifting the coded aperture to a second position relative to the sensor, and forming a second image of the scene through the static coded aperture onto the sensor with the static coded aperture in the second position. Two or more images can be formed in this way. The method includes forming a combined image by deconvolving the two or more images and combining data from the two or more images into the combined image. The combined image can be a more accurate representation of the scene than either of the first and second images.

Abstract: Apparatus and associated methods relate to creating corrected images of a scene for a terminal-imaging seeker using an electrically-controllable coded-aperture mask pattern embodied in a programmable spatial light modulator. The coded-aperture mask pattern includes a plurality of pinhole-like apertures, each of which is configured to perform pinhole-like lensing of the scene. The plurality of pinhole-like apertures form a multiplex of overlapping images on a focal plane array aligned with the optical axis. An image processor reconstructs, based on a configuration of the plurality of pinhole-like apertures and the multiplex of overlapping images, a single image of the scene.

Abstract: An optical system configured to counteract vibrations due to a munitions launch includes a cylindrical optical lens stack. The system also includes an accelerometer attached to the lens stack and connected to a control system and power supply. The system further includes a mechanical actuator attached to the lens stack and connected to a control system and power supply. The mechanical actuator is a piezoelectric actuator.

Abstract: An optical lens stack includes an inner ring of a mounting structure containing axially spaced circumferential lens mounting surfaces on an inside diameter of the inner ring. The inner ring further includes a groove over a fixed axial length on the outer diameter. An outer ring formed to fit over the inner ring contains a groove on the inner diameter of the outer ring that corresponds to the groove on the inner ring and forms a circumferential cavity when the outer ring is mounted on the inner ring. The resulting cavity is filled with an energy absorbing material and serves as a vibration isolator for the lens stack.

Abstract: A muzzle exit tester system comprises a barrel having an input end and an exit end, a shock plunger freely movable within the barrel, and a shock plate having a first side that faces the exit end of the barrel. A support isolation structure resiliently supports the shock plate, and receives a portion of the barrel that includes the exit end of the barrel. A pneumatic shock apparatus is operatively coupled to the input end of the barrel. The pneumatic shock apparatus is configured to retract the plunger in the barrel via a vacuum while producing a gas pressure charge, and subsequently release the gas pressure charge, such that the plunger accelerates to the exit end of the barrel and impacts the shock plate. The shock plate is configured to resonate at frequencies and amplitudes corresponding to a shock condition of a gun muzzle exit when impacted by the plunger.
