Compensation for the non‐uniformity correction of multi‐channel TDI CCD under variable gain
IET Optoelectronics, Volume 15, Issue 1, Page 27-39, February 2021., 2021 Abstract The compensation for non‐uniformity correction of multi‐channel time delay integration charge coupled device (TDI CCD) under variable gain is presented. The mathematical model of photoelectric conversion is established first, and, then, a two‐step non‐uniformity correction method for multi‐channel TDI CCD is proposed.
