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: 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: A stacked circuit card assembly includes a power supply having a positive terminal and a negative terminal, a first circuit card having a first via electrically connected to the positive terminal and a second via electrically connected to the negative terminal, and a second circuit card having a third via aligned with the first via and a fourth via aligned with the second via. The assembly further includes a first conductive stand-off disposed between the first circuit card and the second circuit card and structurally supporting the first circuit card with respect to the second circuit card, and a second conductive stand-off disposed between the first circuit card and the second circuit card and structurally supporting the first circuit card with respect to the second circuit card. The first conductive stand-off provides a conductive pathway between the first via and the third via, and the second conductive stand-off provides a conductive pathway between the second via and the fourth via.

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: 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.
