摘要： An optical system recycles heat from a cooler coupled with an image sensor across a heat transfer element in order to warm and de-ice a window. The optical system may be implemented in high altitude or space vehicles/platforms, regardless of whether manned or unmanned, and the window may be outwardly facing relative to the vehicle/platform so at to allow electromagnetic radiation to pass therethrough onto the image sensor. The optical system enables the reduction of size, weight, and power by recycling heat exhausted from the cooler to warm the window, thus eliminating the need for a separate de-icing system or device for the window.

摘要： Exemplary embodiments provide a method, a system, and a computer readable medium for maintaining detection capability when a frame is corrupted. A plurality of data points of a multispectral gain in a frame is monitored. It is determined that the frame is corrupted by analyzing the plurality of data points. When the frame is corrupted, a single spectrum threat detection system is used instead of a multispectral threat detection system.

摘要： A mechanism for determining atmospheric conditions from an image is described. A mechanism for determining atmospheric conditions includes determining an intensity value for pixels above and below the horizon in an image, calculating a slope between the intensity values for the pixels above the horizon, and a slope between the intensity values for the pixels below the horizon, and determining a difference between the slopes to determine the atmospheric conditions.

摘要： Methods and systems for filtered image data recovery using lookback include storing first, second, and third data captures received from the image sensor in a first memory component and a second memory component. The methods and systems also include identifying a second detection in the second data capture and a third detection in the third data capture by filtering the first, second, and third data captures. The second detection and the third detection each exceed a pixel intensity threshold. The methods and systems also include correlating the second detection and the third detection to identify at least one track. The methods and systems also include detecting a first detection in the first data capture stored in the second memory component, the first detection being a pixel intensity value that is less than the threshold or an initiation event having a pixel intensity value that is less than the threshold.

摘要： Methods, systems, and computer readable media for video image recovery from transient blockage or corruption artifacts include receiving first and second data captures from an image sensor having first and second pluralities of pixel intensity values corresponding to pixel locations of the first and second data captures. The methods, systems, and computer readable media also include identifying in the second data capture, one or more of the second pixel intensity values exceeding a contrast threshold to detect a transient blockage. The methods, systems, and computer readable media also include replacing the one or more of the second pixel intensity values exceeding the contrast threshold with one or more of the first pixel intensity values to generate a corrected data capture.

摘要： An alignment system for sensor or other electrical device filters rate data from gyroscopes and integrates the same to determine an alignment error state that is populated into a direction cosine matrix that pre-rotates measurement from a first electrical device into an estimated coordinate frame to determine a static alignment between first and second electrical devices or sensors. The system may be part of a countermeasure system on an aircraft. A first electrical device may be an inertial navigation system (INS), and a second electrical device may be an inertial measurement unit (IMU). The attitude of the IMU is used to translate the detected threats from the countermeasure system into a common reference frame of the INS.

摘要： A method and apparatus for calculating and accounting for non-uniformity of pixels within an infrared (IR) focal plane sensor utilizing an infrared light emitting diode (IR LED) to wash out environmental infrared light is provided. The IR LED may back propagate through an optical path of an IR sensor to illuminate pixels on a focal plane array, thereby providing data by which the non-uniformity offsets may be calculated and removed for normal operation of the IR sensor.
