专利汇可以提供Panoramic aerial camera专利检索，专利查询，专利分析的服务。并且A panoramic scanning camera adapted to scan a plurality of adjacent narrow transverse strips of the terrain being photographed. Changes of scale, which cause discontinuity between adjacent images, are compensated for by using an optical system which rectifies the image by varying the magnification thereof as a function of the angle between the optical axis and the nadir, viz. the scan angle.，下面是Panoramic aerial camera专利的具体信息内容。

权利要求

1. In a panoramic aerial camera of the type adapted to be carried in flight over the terrain to be photographed, and including scanning means for sequentially photographing a plurality of narrow strips extending substantially transverse to the direction of flight, the improvement comprising anamorphic image rectification means for controlling the magnification of the image only in the direction normal to the direction of scan as a function of the scan angle to provide a constant scale between object and image in the direction normal to the direction of scan.

2. Apparatus as defined in claim 1 including an illuminator adapted to scan said terrain in synchronization with said camera.

3. Apparatus as defined in claim 1 wherein the magnification of the image is varied in direct proportion to the secant of said scan angle.

4. Apparatus as defined in claim 1 wherein said image rectification means includes an arcuate anamorphic lens, the magnification power of which varies continuously from the center of the arc, corresponding to images photographed at the nadir, to the distal portions thereof, corresponding to images photographed at the horizon.

5. Apparatus as defined in claim 1 wherein said image rectification means comprises a pair of spaced lenses positioned along the optical axis of said camera and means for varying the distance between said lenses as a function of said scan angle, said lenses effecting increased magnification of said image as said scan angle increases.

6. Apparatus as defined in claim 1 including an image tube capable of intensifying the camera image received by it, and optical means for relaying the image tube output image to the recording film.
