A method and an apparatus for air-borne or space-borne radiometric measurement of object points present in an object scene on the surface of a astronomical body. A corrected recording of image points in an image plane in which object points from the object scene are imaged on a detector, is carried out by determining recording errors of the detector caused by systematically occurring spatial and temporal changes in a scanning movement of the detector, with reference to a measurement line relative to a recording field, then generally an actuation function along the measurement line in the form of different trigger times in which measurements of the individual object points are initiated exactly at that time. Based on the triggering of the detector elements due to the actuation function synchronized measurements of all of the object points of every row of an object matrix are carrying out along the designated measurement line.

Method and apparatus for the corrected radiometric measurement of object points on surfaces of astronomical bodies

The invention is directed to a method and an apparatus for air-borne or space-borne radiometric measurement of object points present in an object scene on the surface of an astronomical body which are assigned to rows and columns of an object matrix during a scanning progressing systematically in a first scanning direction and a second scanning direction, wherein the object matrix points are imaged on a detector in an image plane generated by optics, and the image inside the image plane is recorded by at least one radiation-sensitive detector element of the detector.
