Investigation of Optical Processing, Holography and Interferometry with Femtosecond Pulses.
Abstract
A variety of methods were developed for imaging through highly scattering material, such as biological tissue. The aim is to be able to see objects hidden within the material. The techniques use advanced electronic cameras that are cooled to very low temperature, as well as considerable computer processing. Experimental results show these methods to be highly effective. In addition, we developed new techniques in confocal imaging, including a method for enhancing the depth discrimination capabilities of the process. Finally, we extended a technique we developed earlier: the transmission of three dimensional images through, single, single mode optical fibers using monochromatic light. The imaging process works on the basis of optical coherence, hence the process is called coherence imaging.
