Claim Text:
1. A method of misregistration correction in a line scanning imaging system, comprising: providing the line scanning imaging system with a forward array of optical detectors and a trailing array of optical detectors for receiving optical signals from a scene being scanned and converting the optical signals into electrical signals, the forward array of optical detectors receiving the optical signals at a different time than the trailing array of optical detectors receiving the optical signals, the forward array of optical detectors and the trailing array of optical detectors defining a plurality of detector junction overlap regions; receiving the electrical signals at a processor; processing the received electrical signals with the processor, the processing comprising the steps of: the steps of generating a model of scan motion, estimating programmed motion positions, measuring actual motion positions, generating differences, estimating updates, generating corrections and applying the updates are performed by means of a non-transitory computer-usable medium having computer-readable code that, when executed by the processor, cause the processor to perform the steps.
