Abstract
AbstractImaging concealed objects with a millimeter‐wave coherent beam is accompanied with speckle. Two tools were chosen to improve visibility of concealed objects for security or industrial inspection: a speckle contrast image (image processing tool) and a Hadamard diffuser (mechanical tool). We report more then 50% speckle reduction over the full W‐band. © 2007 Wiley Periodicals, Inc.
