Abstract

We review the history of time gated imaging, and summarize the method of Chrono-Coherent Imaging (CCI) that we have developed for imaging inside of scattering media such as tissue. We present experimental data on the time evolution of coherence properties in a scattering media that define some practical limitations of CCI and other coherence dependent imaging methods in transmission and reflection geometries. These data include results with well phased mode locked lasers and random phased microsecond dye lasers having femtosecond coherence. We also discuss the transformation of coherence in space and time in a scattering media, and use this analysis to suggest some new research directions.
