Coherence imaging by use of a Newton rings sampling function

Podoleanu, Adiran G., Dobre, George M., Webb, David J. and Jackson, David A. (1996). Coherence imaging by use of a Newton rings sampling function. Optics letters, 21 (21), pp. 1789-1794.


We show that, with suitable optics in the arm of a Michelson interferometer, orthogonal galvo-scanning mirrors build a sampling function in the form of Newton rings when the two interferometer arms are matched. Using a low-coherence source, one can obtain transversal depth-resolved images. A fast display procedure using a storage oscilloscope was devised based on this method.
