Abstract
Many line-scan remote sensing sensors utilize multiple stages of time delay and integration to enhance the final image signal-to-noise ratio. The swath width of these systems can be limited by optical distortion, which causes nonlinear image scanning and results in image smear at the edge of the field-of-view (FOV). Newly developed orthogonal transfer charge-coupled device arrays, with the ability to shift pixel charges in any direction, can be used to compensate for the smear caused by optical distortion in this scenario. In this paper we present example results for this approach with simulated data from a wide FOV sensor.
