Passive background correction method for spatially resolved detection

DWPI Title: Method for background correction of spatially and spectacularly resolved detection of emission in light detection and ranging system, involves correcting target region signal, to obtain background corrected target signal
Abstract: A method for passive background correction during spatially or angularly resolved detection of emission that is based on the simultaneous acquisition of both the passive background spectrum and the spectrum of the target of interest.
Use: Method for background correction of spatially and spectacularly resolved detection of emission in light detection and ranging (LDAR) system used in remote sensing application.
Advantage: The passive background correction of emission in the LDAR system can be improved, so that interleaving of the passive background data can be avoided. Hence the uncertainty in the magnitude of the actual signal can be eliminated.
Novelty: The method involves illuminating (10) a target region with an excitation beam. The set of pixels of the detector array is determined (13), by the divergence angle of the excitation beam. The determined set of pixels of the detector array is collected. Another set of the pixels of the detector array is collected (14), by generating background signal form a background light. The target region signal is corrected (15), using the background signal, to obtain a background corrected target signal.
