Abstract

3D images have been formed through a pair of single mode fibers, using monochromatic light of reduced spatial coherence. Two fibers are required: one carries the object beam, the other the reference beam. Light comes out of the exiting end of the two fibers, interferes to form a hologram, which then forms a fully 3D image. Also, we have pursued the problem of imaging through highly scattering media, such as biological tissue. We recover both the amplitude and the phase of the uncorrupted wavefield from the scattered light. This is accomplished with considerable effort; we record up to 8000 electronic holograms and read them all into a computer; the resulting computer processing is quite intensive, requiring many hours of computing. With the phase thus recovered, we can get significantly improved image resolution.
