摘要： A method of correcting an infrared image is provided. The method includes receiving an image from a camera comprising a first pixel with a first pixel value and a neighbor pixel with a neighbor pixel value. The first pixel and the neighbor pixel can be assumed to view the same object. The method further includes storing the first and neighbor pixel values in an image table, generating a corrected image table by adding the first pixel value to a corrected pixel value in a correction table, determining that the camera is not moving, and masking edges in the corrected image table. The method further includes updating the correction table by: determining that the first pixel value and neighbor pixel value are not edges, computing the difference between the first and neighbor pixel values, and storing the difference in the correction table. The method further includes providing an output image table.

摘要： An apparatus includes a detector that measures radiation. The apparatus also includes a window that is relationally coupled to the detector and a shield, so that the window is in between the detector and the shield. The apparatus further includes the shield that emits substantially constant radiation, and substantially blocks radiation from a camera housing at least partially surrounding the shield, so that the detector measures radiation passing through an optical system and the shield.

摘要： Systems, devices, and methods are disclosed for testing the boresight of a gimbaled camera and laser system, such as an infrared countermeasures (IRCM) system, in extreme environments. Light simulating a target is reflected through an optics system to the camera, with a portion of the light reflected back from a corner cube reflector through the optics system as a reference. A laser beam from the laser is received through the same optics system, and a position of the corner cube reflected reference and laser beam are compared in order to determine whether the camera and laser are properly aligned. A spherical shell adapted to position the camera at its geometric center keeps misaligned laser pulses from reflecting back into the camera.

摘要： A vibration isolator system for attaching a payload to a supporting base is provided, the payload having a center of mass and the system consisting of at least three vibration isolating pods. Each pod has two associated, non-parallel, elastic struts. A first end of each strut is attached to the supporting base and a second end of each strut is attached to the payload at a respective mounting point, and the a projected elastic center of the system is substantially co-located with said center of mass. The vibration isolator system is operable to substantially prevent translational vibration of the supporting base from inducing angular rotation of the payload.

摘要： Embodiments are directed to systems and methods for blind image deconvolution. One method of blind image deconvolution comprises capturing a video using an imaging device and measuring a sharpness degradation metric for the video. The method further comprises determining parameters of a point spread function (PSF) corresponding to the sharpness degradation metric using a predetermined equation and performing deconvolution on at least one frame of the video using the PSF and the determined parameters.
