HIGH RESOLUTION DEPTH RESOLVED IMAGING THROUGH SCATTERING MEDIA USING TIME RESOLVED HOLOGRAPHY

摘要

We report on time-gated holographic imaging at 450 nm using photorefractive media to achieve high depth and transverse resolution through a turbid medium. Using 70 fs pulses from a frequency-doubled mode-locked Ti:sapphire, we have demonstrated that both depth and transverse spatial resolution of 50 mu m are achievable through a depth of 10 scattering mean free paths. Whole-field depth-resolved 2-D image planes were acquired in a single integration of a few seconds. [References: 14]
