title: Comments on "Design and characterization of thin multiple aperture infrared cameras".
abstract: Recent analysis of a spatially multiplexed flat camera concept [Appl. Opt.48, 2115 (2009)] contains factual errors. Specifically, a performance metric and related signal-to-noise ratio analysis from an earlier work [Appl. Opt.45, 2901 (2006)] are inappropriately altered and incorrectly applied, and then associated with analytical and experimental results that cannot be properly interpreted. This comment corrects the misrepresentations.
