TL;DR: In this article, a brief comparison of pre-flight laboratory results vs. in-flight performance is given, including quantum efficiency and noise, as well as a discussion of irregular effects, such as residual image performance, first frame effect, banding, column pull-down and multiplexer bleed.
Journal ArticleDOI
Numerical model estimating the capabilities and limitations of the fast Fourier transform technique in absolute interferometry.
TL;DR: By processing computer-simulated data through this model, the ultimate precision for ideal data, and data containing AM-FM noise, is project, which is shown to be limited by nonlinearities in the laser scan.
