摘要： An aerial reconnaissance camera system is disclosed which compensates for atmospheric dispersion. The dispersion is principally a function of the observing altitude and slant range and occurs in the camera depression direction only. The effective spectral dispersion of the atmosphere is shown to be about 15 microradians over the visible/near infrared spectrum (500 to 900 nanometers) at typical long range oblique photography (LOROP) imaging ranges. Consequently, dispersion is compensated by means of a fixed optical wedge incorporated into the optical path of the reconnaissance camera, e.g., in a fixed reconnaissance window. The wedge has dispersive qualities opposite to the effective net dispersion of the atmosphere for an expected reconnaissance mission using the camera.

摘要： An electro-optical imaging array provides compensation for image motion due to variations in scene terrain electronically and with no moving parts. Pixel information representing scene information is transferred through the array in column groups. Each column group has its own charge transfer rate U. Successive images of the scene are generated by the imaging array, and the images are correlated by electronic signal processing circuitry to determine the image displacement of a fixed point in the scene between successive images. The image displacement is used to calculate a residual image velocity U.sub..delta. in each column group. As successive images of the scene are generated, the charge transfer rates U for each column group are updated, whereby U=U.sub.0 -U.sub..delta., where U.sub.0 is the charge transfer rate for the previous exposure, and U.sub..delta. is the residual image velocity in each column group.

摘要： A camera system is described which is based on an electro-optical imaging array performs electronic image motion compensation without moving parts during a reconnaissance maneuver in which the aircraft is experiencing a non-zero rate of change in the pitch axis, such as in a dive bomb maneuver when the pilot is pulling out of the dive. The camera system has a camera control computer that calculates a pixel information transfer rate for the array based on parameters supplied by the aircraft's navigation system and pre-mission known parameters, including the aircraft's velocity, height above ground, attach angle, pitch angle, and rate of change in pitch during the period in which the array is taking successive exposures of the scene. The camera control computer supplies information to the drive and control electronics that control the transfer of pixel information in the array. In a preferred embodiment, the array is exposed to the scene of interest in a series of rapid exposure intervals and generates a frame of imagery during each exposure. By virtue of the electronic image motion compensation, each frame of imagery is a high resolution image of the scene of interest, far surpassing images created by an electro-optical array if the present image motion compensation technique were not performed.

摘要： An aerial reconnaissance camera and method provides for generating a first image of the terrain of interest with the camera pointing angle oriented or rotated about an azimuthal axis some angular amount (&thgr;1) to a first, typically forward orientation, i.e., forward of a cross-line of flight direction. An image is obtained of the ground at this orientation. Then the camera is rotated about the azimuthal axis to new angular value (&thgr;2), which will typically be aft of the cross line of flight direction. An image is generated at this value. The camera is then rotated back to the value of &thgr;1, and a second image in the forward orientation is generated. The camera is then rotated again to the value of &thgr;2 and another image in the aft orientation is generated. This process of rotating the camera about the azimuthal axis and generating images in forward and aft orientations continues over and over. Eventually, as the aircraft flies past the terrain of interest, any given location in the terrain of interest will have been imaged from two different perspectives—forward and aft. The motion of the aircraft during the interim in combination with the values of &thgr;1 and &thgr;2 provide the high baseline for the stereo image pairs. By selection of suitable values for the angular separation of &thgr;1 and &thgr;2 (such as &thgr;1=+10 degrees and &thgr;2=−10 degrees) the result will be pairs of images of the terrain of interest having a large baseline, producing truly high aspect stereo images from a single camera. The method also works in a similar fashion by rotation back and forth about the pitch axis and imaging the terrain in forward oblique and aft oblique orientations.

摘要： An electro-optical imaging array having pixels arranged in rows and columns electronically compensates for image motion in the plane of the array regardless of whether the motion vector is in the row direction, the column direction, or in a diagonal direction, i.e., in some vector combination of row and column directions. In an aerial reconnaissance application, the image motion may be due to rotation of the aircraft about roll, pitch and/or yaw angles in addition to forward velocity of the aircraft. The image motion compensation is achieved with no moving parts and does not require a stabilized platform. A camera control computer determines the magnitude and direction of the image motion from inertial navigation system inputs, including velocity, flight, and aircraft rotation information, and calculates pixel information transfer rates in the row and column directions. The pixel information transfer rates are supplied to a counter and clock driver circuit for the array. The pixel information in the array is transferred in the row and column direction in a step-wise fashion in the row and column directions at a rate and direction substantially matching the image motion. The array itself is provided with a gate and control line design to enable charge representing pixel information to be transferred in both the row and column directions.

摘要： An electro-optical step-frame camera system in which successive overlapping frames of scene imagery are generated by an electro-optical imaging array, and in which electronic image motion compensation is performed by the array during the generation of at least some of the frames of imagery. The successive frames of imagery are made in a stepping pattern that is repeated in a series of cycles of steps, each step separated by a framing interval in which a frame of imagery is obtained. The stepping cycles of the camera generate sweeping coverage of the terrain of interest. As the velocity to height ratio of the reconnaissance aircraft changes, the stepping cycle and electronic image motion compensation are continually adjusted, so as to ensure maximum scene coverage and preservation of image resolution.
