Abstract

The paper investigates the imaging response of cw coherent systems for imaging through scattering media. Particular attention is paid to the confocal optical technique, and experimental results are presented that show the effect on the imaging spatial resolution as the optical configuration is altered. It is seen that if the scattering concentration is increased, there is a sudden reduction in spatial resolution. This point defines a so called transition region. We show how this transition region can be moved by altering the optical configuration. We also see that when heavily scattering media is being examined, it is possible to vary the optical configuration, what is in effect changing the optical response to various scattered components of light. This procedure can be likened to adjusting the time window in the pulsed time of flight technique, and is further investigated in the companion paper.
