Abstract
In this paper authors show the application of low coherence interferometry and optical coherence tomography with non-Gaussian light source, which are applicable in simultaneous measurement of micromembrane and detection of layers deposited on silicon wafer. The exemplary measurement results obtained with laboratory setup are presented. Full Text: PDF References D. Huang, et al. "Optical coherence tomography", Science, Vol. 254, 1178 (1991). CrossRef A.
