20130148104 | ADVANCE SPATIAL AND SPECTRAL TARGET GENERATION FOR HARDWARE IN THE LOOP SYSTEMS - A system comprises a micro-mirror device including a surface having a plurality of micro-mirrors movable to reflect light incident to the micro-minors in at least a first direction and a second direction, a control circuit configured to arrange the micro-mirrors to project a spatial image using the incident light and to generate spectral content for the formed spatial image, and a spectrometer circuit configured to extract spectral image information from the generated spectral content and provide the spectral image information to the control circuit. The spectral content includes light having one or more wavelengths outside a range of wavelengths for visible light, and the control circuit is configured to rearrange one or more micro-mirrors of the micro-mirror device to adjust spectral content based on the extracted spectral image information, | 06-13-2013 |
20140063577 | INFRARED LASER HOLOGRAPHIC PROJECTOR - Systems and methods for infrared laser holographic projection. In one example, an optical apparatus includes a first laser source configured to generate a first laser beam having a first wavelength in an infrared spectral range and a holographic medium optically coupled to the laser source and having a transmittance range including the first wavelength. A diffraction pattern formed in the holographic medium encodes an input image and is configured to diffract the first laser beam responsive to being illuminated by the laser beam so as to construct an image in the infrared spectrum, the image being a reconstruction of the input image. The diffraction pattern may further be configured to diffract a second laser beam having a second wavelength in a visible spectral range to construct an image including a first portion in the infrared spectral range and a second portion in the visible spectral range. | 03-06-2014 |
20140117260 | GREY-SCALE HOLOGRAPHIC STRUCTURE AND SYSTEM FOR GENERATING A MILLIMETER-WAVE COLLIMATED WAVEFRONT IN A COMPACT RANGE - Embodiments of a grey-scale holographic structure and system for generating a collimated wavefront in a compact range are generally described herein. In some embodiments, the grey-scale holographic structure comprising millimeter-wave transmissive material having a surface arranged to provide differing amounts of phase-delay to an incident millimeter-wave wavefront as the incident wavefront passes through the material. The grey-scale holographic structure may comprises a plurality of layers (N) to provide a phase total delay of lambda which results from a series tuned layers, each having a thickness of a wavelength/N. Each layer provides a predetermined amount of phase delay allowing the structure to operate as a phase-delay hologram. | 05-01-2014 |

20140355085 | INFRARED HOLOGRAPHIC PROJECTOR FOR THERMAL MASKING AND DECOYS - A holographic structure, system and method project a grey-scale image in a narrow IR spectral band that is related to a broadband thermal signature of an object. The projected grey-scale image, when integrated over the broadband, forms either a decoy that approximates the thermal signature of the object or a mask that obscures the thermal signature of the object. The projected image is a tuned phase recording of a desired far field projection. In different embodiments, the projected image is a “positive” or a “negative” image of the object's thermal signature, a difference image between the thermal signatures of a false object and the object or a camouflage image of random features having approximately the same spatial frequency as the object's thermal signature. The goal being to confuse or fool, even for a short period of time, the warfighting or surveillance system or human observer that uses a broadband IR sensor to acquire and view thermal images of the scene. | 12-04-2014 |
20150198418 | FIELD BORESIGHTING USING HOLOGRAPHIC LASER PROJECTION - Systems and methods for boresighting a weapon having a barrel and at least one component to be aligned with the barrel. In one example, a boresighting apparatus includes a housing configured to attach to the weapon so as to lock the boresighting apparatus in a stationary position relative to the barrel, and a holographic laser projector contained within the housing and configured to project an image, the image including at least one boresighting target, each boresighting target of the at least one boresighting target having a geometric shape selected according to a component of the at least one component so as to permit alignment of the component with the barrel. | 07-16-2015 |
20160083117 | DYNAMIC TESTING OF ATTITUDE DETERMINATION AND CONTROL SYSTEMS, REACTION WHEEL AND TORQUE RODS USING AUTOMOTIVE ROBOTIC TECHNIQUES - A fully automated method for testing functionality of a spacecraft or aircraft unit under testing (UUT) includes selecting a test station at which to conduct a first functionality test on the UUT. The method also includes coupling a program specific module (PSM) to the UUT. Each PSM is configured to couple to a specific type of UUT to provide power and telemetry to the specific type of UUT. The method further includes a robot arm moving the UUT to the selected test station. The method still further includes conducting the first functionality test on the UUT at the selected test station. | 03-24-2016 |
