摘要： To calibrate a tracking system, a computing device receives positional data of a tracked object from an optical sensor as the object is pointed approximately toward the optical sensor. The computing device computes a first angle of the object with respect to an optical axis of the optical sensor using the received positional data. The computing device receives inertial data corresponding to the object, wherein a second angle of the object with respect to a plane normal to gravity can be computed from the inertial data. The computing device determines a pitch of the optical sensor using the first angle and the second angle.

摘要： A system and method for moving target based non-uniformity calibration for optical images. The described approach allows for the use of the same test chamber to perform non-uniformity calibration and moving target tests. The current approach works by scanning a test scene having a target and a background at different intensity levels in an overlapping pattern across the imager FOV and cross-referencing multiple measurements of each pixel of a test scene as viewed by different pixels in the imager; each fully-compensated image pixel sees multiple different scene pixels and each scene pixel is seen by multiple imager pixels. For each fully-compensated imager pixel, an Nth order correlation is performed on the measured and estimate pixel response data to calculate the NUC terms. This approach is based on the simple yet novel premise that every fully-compensated pixel in the array that looks at the same thing should see the same thing.

摘要： Method and apparatus for determining the location at which radiation is incident on the sensor system which includes an EMI screening mesh by comparing the actual image detected, which includes the higher order diffraction effects, with a search or sample image applied sequentially at different locations and determining the location of the sample image which gives the closest match. The sample image corresponds to an expected pattern or image from a point source incident at a particular location on a particular window/sensor system, and may be generated from a real source of known location and properties incident on the system, or may be a generated image, such as a standard image such as a cross pattern or determined mathematically, for example using Fourier transforms. Preferably, once the location of the point of incidence of the radiation has been determined, image processing techniques are applied to remove the diffraction spots.

摘要： A device for detecting laser beams where high levels of light from an extraneous source may be present in one area of the device's field-of-view. The device has a lens (3) to focus an image of the field-of-view onto a surface of a photodetector (1) and an optical limiter (2) is located between the lens (3) and the photodetector (1). The optical limiter (2) limits transmission of the light received from the extraneous source at areas of the optical limiter (2) onto which the light is focussed by the lens (3) but remains transmissive to the laser beams and light received from other areas. The device is particularly intended for use in laser warning receivers where sunlight (S) may be focussed on the optical limiter (2) and blocked at the particular area (5) of the optical limiter (2) onto which it is focussed. The optical limiter (2) does not block laser beams allowing them to be detected by the photodetector. An imaging system using the same optical arrangement can also be used in video cameras to specifically attenuate the effects of the sun on a charge coupled device (CCD) image sensor.

摘要： The present invention provides for simple and streamlined boresight correlation of FLIR-to-missile video. Boresight correlation (42) is performed with un-NUCed missile video (40), which allows boresight correlation and NUC (46) to be performed simultaneously thereby reducing the time required to acquire a target and fire the missile. The current approach uses the motion of the missile seeker for NUCing to produce spatial gradient filtering in the missile image by differencing images as the seeker moves. This compensates DC non-uniformities in the image. A FLIR image (44) is processed with a matching displace and subtract spatial filter constructed based on the tracked scene motion. The FLIR image is resampled to match the missile image resolution, and the two images are preprocessed and correlated using conventional methods. Improved NUC (46) is provided by cross-referencing multiple measurements of each area of the scene as viewed by different pixels in the imager. This approach is based on the simple yet novel premise that every pixel in the array that looks at the same thing should see the same thing. As a result, the NUC terms adapt to non-uniformities in the imager and not the scene.
摘要翻译：本发明提供了FLIR对导弹视频的简单和简化的视轴相关性。使用非NUCed导弹视频（40）执行视轴相关（42），这允许同轴执行视轴相关和NUC（46），从而减少获取目标并发射导弹所需的时间。目前的做法是使用导弹探测器进行NUCing的运动，通过在寻像者移动时通过差分图像来在导弹图像中产生空间梯度滤波。这补偿了图像中的DC不均匀性。 FLIR图像（44）用匹配的移位和减去基于跟踪的场景运动构造的空间滤波器来处理。 FLIR图像被重新采样以匹配导弹图像分辨率，并且使用常规方法对两个图像进行预处理和相关。改进的NUC（46）通过交叉参考在成像器中的不同像素观看的场景的每个区域的多个测量来提供。这种方法是基于简单而又新颖的前提，数组中的每个像素看起来都是相同的东西。因此，NUC术语适应成像器中的不均匀性而不是场景。
