Method of Increasing the Level of Contrast of Diffraction Extrema in Probing Deep Through Holes

A method of inspecting deep (lengthy) millimeter-range holes over near-field zone diffraction orders and a technique of constructing analogous diffraction patterns from the inlet and exit planes of the hole for two different wavelengths are considered.[PUBLICATION ABSTRACT]
