Hadamard speckle reduction for millimeter wave imaging This publication appears in: Microwave and Optical Technology Letters Authors: I. Jäger, J. Stiens, G. Koers, G. Poesen and R. Vounckx Volume: 48 Issue: 9 Pages: 1722-1725 Publication Date: Jun. 2006
Abstract: Millimeter wave imaging technology makes possible imaging of phenomena, which are inaccessible to visible light, but suffer from speckles, produced by coherent sources. We report a 50% speckle reduction, measured with a free-space vector network analyzer over the full W-band. Our experiments demonstrate how Hadamard mask operates as a tunable filter. External Link.
