Array scanner noise reduction system

摘要

An optical scanner system scheme is described that enables better detection limits to be reached at the highest resolution of a fluorescent imager. In a scanner that has asymmetric scan qualities, measurement errors are eliminated by a factor that is greater than expected for simply handling random errors through additional sampling. Systematic asymmetries in scan direction are factored out by averaging pixel results obtained from opposite direction scans of the same line and binning them together at the same resolution.
