title: Zernike test. 1: Analytical aspects.
abstract: The Zernike test is extensively interpreted from an interferometric point of view. The discussion includes the optimization of the Zernike disk parameters (radius, phase, and transmittance) for low-order aberrations, and a method is provided for choosing the disk parameters so as to optimize test performance for maximum sensitivity and linear range. A signal-to-noise analysis predicts test sensitivity to be better than lambda/100.
