Imaging with short optical pulses

Abstract A new method of three-dimensional optical imaging based on range gating with subpicosecond pulses is being developed. As opposed to other techniques of medical imaging, this new method is characterized by both high contrast and resolution. Preliminary tests demonstrate a longitudinal resolution better than 10 μm. The computer algorithm needed to reconstruct the image from the attenuated backscattering and to extend to three dimensions the one-dimensional depth resolution, is discussed.
