Abstract

Johnson's comments [Appl. Opt. 46, 4162 (2007)] represent a nice independent analytical proof of a specific aspect of the Ben-David and Ren [Appl. Opt. 44, 3846 (2005)] general analysis in which the effect of noise-angle statistics on the accuracy of the two techniques was addressed and demonstrated. When whitening is applied to the data, the noise-angle distribution becomes effectively uniform and is thus consistent with the predictions that the subtraction solution becomes superior to the orthogonal subspace projection solution.
