摘要： A dual band hyperspectral framing aerial reconnaissance camera includes an objective optical subassembly for receiving incident radiation from a scene external of the vehicle, and a dividing element receiving radiation from the objective optical subassembly. The dividing element directs radiation into a first optical path for imaging in a first band of the spectrum and a separate second optical path for imaging in a second band. A first two-dimensional electro-optical detector in the first path generates a first series of images and a second two-dimensional electro-optical detector in the second optical path generates a second set of imagery. At least one of the first and second electro-optical detectors comprises a hyperspectral imager.

摘要： A reconnaissance camera is described which has a Cassegrain optical system forming an objective lens that directs radiation to a spectrum-dividing prism. The prism directs radiation in a portion of the electromagnetic spectrum (e.g., visible) into a first optical path having a two-dimensional image-recording medium. Radiation in a second band of the spectrum (e.g., IR or UV) is directed to a second optical path, which has a two-dimensional image-recording medium. A motor system is coupled to a camera housing that encloses the optical elements of the camera and the image recording media. The motor steps the entire camera housing about the roll axis while the image recording media are exposed to generate frames of imagery.

摘要： A framing aerial reconnaissance camera is described which has a Cassegrain optical system forming an objective lens that directs radiation to a spectrum-dividing prism. The prism directs radiation in the visible portion of the electromagnetic spectrum into a first optical path having a two-dimensional image-recording medium, such as a framing CCD array. Radiation in the infrared (IR) band of the spectrum is directed to a second optical path, which has a two-dimensional framing IR-sensitive image-recording medium. The entire camera can be either rotated about the aircraft roll axis in a continuous fashion or stepped in a series of steps to generate frames of imagery, providing panoramic coverage of the scene across the line of flight in two bands of the spectrum simultaneously.

摘要： A dual band optical system for a framing aerial reconnaissance camera is described. The camera including at least two two-dimensional image recording media for generating frames of imagery of a scene external of an aerial reconnaissance vehicle carrying the camera. The camera includes a Cassegrain optical system forming an objective lens for the optical system, including a a primary mirror having a central aperture and a secondary mirror. The primary and secondary mirrors are aligned along an objective optical axis. The optical system also includes an azimuth mirror receiving radiation from the secondary mirror. The azimuth mirror is placed between the primary and secondary mirrors. A spectrum-dividing element in the form of a prism receives radiation from the azimuth mirror. The spectrum-dividing element directs radiation in a first band of the electromagnetic spectrum into a first optical path and radiation in a second band of the electromagnetic spectrum into a second optical path different from the first optical path. A first two-dimensional image recording medium is placed in the first optical path and a second two-dimensional image recording medium is placed in the second optical path. The first and second image recording media generating first and second images in two different portions of the electromagnetic spectrum simultaneously.

摘要： An electro-optical roll-framing camera is described in which successive overlapping frames of scene imagery are generated by an electro-optical imaging array. Image motion compensation is performed electronically to stop or freeze image motion caused by the roll motion. The image motion compensation is performed by the array during the generation of the frames of imagery. The successive frames of imagery are made during a continuous roll motion of the entire camera (including the array). The image motion due to roll is stopped or frozen without mechanically stopping the roll motion, such as found in prior art step frame cameras. The roll framing cycles of the camera generate sweeping coverage of the terrain of interest. The roll rate for a given electro-optical array is a function of the frame size and the framing rate, and is controllable by a master camera control computer.
