Patent ID: 8860951

Claim:
A method for air-borne or space-borne radiometric measurement of object points i mn present in an object scene on a surface of an astronomical body which points are assigned to rows m and columns n of an object matrix O mn during a scanning progressing systematically in a first scanning direction and a second scanning direction, comprising the steps of: imaging the object points i mn into an image plane on a detector as image points B mn , recording the image points B mn inside the image plane by at least one radiation-sensitive detector element of the detector; determining, prior to the start of a measuring process, systemic imaging errors of the image points B mn with reference to a designated measurement line along which the image points B mn are acquired, as relative positional deviations ΔL i of the image points B mn from the measurement line; generating an actuation function A(ΔL i ) based on the relative positional deviations ΔL i along the measurement line in the form of trigger times in which measurements of the individual object points i mn are initiated at different times, wherein the trigger times are so defined along the measurement line that the measurement of every object point i mn is carried out when the image point B mn thereof corresponds spatially to a detector element assigned to the measurement line; storing the actuation function A(ΔL i ) and making it accessible to a detector control unit associated with the detector for successive measurements along the measurement; and carrying out synchronized measurements of all of the object points of every row i mn of the object matrix O mn along the designated measurement line based on the triggering of detector elements due to the actuation function A(ΔL i ).
