Abstract: A method of image processing for finding a target in a scene includes receiving a series of images from a sensor and computing a background relative velocity in the series of images. The method further includes estimating a hypothesized target relative velocity of the target in the series of images. The method further includes computing a target revisit time based on a difference of the target relative velocity and the background relative velocity. The method further includes adjusting one or more of a frame capture rate or a frame processing rate based on the target revisit time.

Abstract: A mirror system is disclosed. The mirror system can include a primary mirror, and a secondary mirror supported relative to the primary mirror. The primary mirror and the secondary mirror can have different coefficients of thermal expansion (CTE). A negative CTE strut is also disclosed. The negative CTE strut can include a main body portion. The negative CTE strut can also include a first coupling portion and a second coupling portion disposed opposite one another about the main body portion and defining a strut length. The first and second coupling portions can each be configured to interface with an external structure. In addition, the negative CTE strut can include an offsetting extension member having a first end coupled to the main body portion and a second end coupled to the first coupling portion by an intermediate extension member. The first end can be between the first coupling portion and the second end. The first and second ends can define an offset length parallel to the strut length. When the negative CTE strut increases in temperature, the offset length can be configured to increase due to thermal expansion of the offsetting extension member sufficient to cause the strut length to decrease.

Abstract: Described are methods and systems for vicarious polarimetric calibration and performance validation of a remote sensor. The system includes a plurality of reflective mirrors configured and arranged to reflect radiation from a source of radiation onto the remote sensor with accurately known polarimetric properties. Each of the reflective mirrors are located so that the target images do not overlap. The remote sensor is configured to receive the radiation reflected from the plurality of reflective mirrors and store the received radiation as image data (e.g., the image of each mirror appears as a point target). The system includes a processor configured to process the received data to provide direct calibration and performance validation for each polarimetric or spectral channel of the remote sensor. In addition, the calibration method removes all atmospheric effects except for transmittance and provides reference targets that have high polarimetric contrast, full spectrum performance and easy to deploy.
