Abstract
The light beam wave front form is often base to complete accurate parameter calculations of such objects under test as optical systems and components, transparent and reflecting materials, man-made radiation souses and so on. The adequacy of measured data to reconstruct wave front form and technical practicability of various optical measuring systems are analyzed to determine applicability of such methods and devices as Hartmann Method, Wavefront Sensing by Pseudo Phase-Conjugate Interferometry, Talbot Method, Phase Modulation Method, Linnik Interferometer and Shearing Interferometry. Information losses of wave front spatial frequency spectrum are determined on mention methods and optical systems. Experimental data and end-use measurements are submitted.
