title: Wave-front tomography by Zernike polynomial decomposition.
abstract: By making a series of wave-front observations that differ in angle and degree of collimation and using subaperture testing theory, the Zernike polynomial representation of several aberrating screens may be determined from external measurements of the optical system. In this Letter, the analytical basis is presented, limitations to the technique are explored, and some results of numerical evaluation are described.
