Thick TIR forms of this technique are described by Herwig Kogelnik’s coupled wave theory. R. F. van Ligten pioneered the “corrected optics” approach to this technique. Möllenstedt and Düker invented an electron biprism in an off-axis scheme for this technique. The displacement of a surface is mapped by the “frozen-fringe” form of this technique. It’s not X-ray diffraction, but in- and (*) off-Bragg schemes are used in this technique. Dichromatic gelatin is the most common material used to produce this technique’s “optical elements.” In this technique, reconstruction is applied to an image generated on a recording material by an object beam and a reference beam. (10[1])Dennis Gabor (10[1])invented this technique (10[1])to improve the resolution of electron microscopy. For 10 points, name this technique that creates a three-dimensional image of an object. ■END■ (10[3])
