Abstract
simple upconversion scheme utilizing 40-fs pulses is shown to permit high-c ontrast imaging of objects obscured by a highly scattering medium when no b allistic component is evident in the scattered light and imaging is perform ed with any portion of the scattered light pulse. We present a time-gated, inherently low-pass spatially filtered imaging method that minimizes signal -averaging requirements and greatly facilitates imaging under severe scatte ring (turbid) conditions.
