Abstract: A method and a device for imaging with high geometrical resolution on a microsatellite. The device includes an objective and a focal plane on which an extended optical detector is fitted. The objective and the focal plane being fastened rigidly to the microsatellite. Intermediate optics, which can be moved using a setting and resetting instrument, are arranged between the objective and the focal plane.

Abstract: A device for the geometric calibration of a CCD camera, which includes a coherent light source and a synthetic hologram arranged relative to the coherent light source so that the hologram generates a real three-dimensional test structure f(x,y,z) around a focal plane of the CCD camera using coherent light. A method for geometric calibration of a CCD camera using a coherent light source and a synthetic hologram which includes the steps of calculating the synthetic hologram to provide a well-defined ideal three-dimensional test structure f(x,y,z) taking into account idealized camera optics of the CCD camera to be calibrated, illuminating the hologram using the coherent light source so that a real three-dimensional test structure f(x,y,z) is generated around a focal plane of the CCD camera, and evaluating in parallel a plurality of sensor pixels by determining a respective section plane through the real test structure f(x,y,z) from individual image information of each of the plural sensor pixels.

Abstract: A method for archiving a master image, including the steps of pre-detecting a resolution of a master image which is at least one of a geometric, a radiometric and a spectral resolution, adaptively matching a resolution of an optical device to the pre-detected master image resolution such that the optical device resolution conforms with minimum resolution for an appropriate scanning theorem, scanning point values of the master image with the resolution from the matching step by the optical device having a photosensitive component, digitizing the point values of the master image from the scanning step, compressing the digitized point values, and storing the compressed point values.
