Correction of the effects of the alternating voltage coupling in a train of a scanning opto - electronic sensors

摘要

in a method for correcting influence of the wechselspannungskopplung in a signaling abtastender, opto - electronic sensors on the radiometric image will be $(a) characteristic time (i) from the time constant (t, 0) of a rc limb of each spectral channel (i) the wechselspannungsgekoppelten signaling.a zeilenabtastfrequenz (f0) and the number of picture elements (pixels) per line (p) is determined and stored, $a (b) for each element of a spectral sensorkanals (i) with its characteristic time (i) in the form of a wechselspannungsgekoppelten signaling a vorkorrektur rek ursiven, inverse rc filtering abtastwerte performed $a (c) the recursive inverse rc filteredvorkorrigierten image spectral channel and transversely cached and $a (d) in the case of the use of external radiation is completely independent bildabtastwerte dunkelreferenzquelle corrected on the basis of the vorkorrigierten and cached image data with the help of fo r every channel (i) on sensorausgang present dunkelreferenzsignalen immediately and directly calculated.
