Double-stage picosecond Kerr gate for ballistic time-gated optical imaging in turbid media.
We demonstrate that use of a picosecond double-stage Kerr gate system results in a 3-orders-of magnitude improvement in signal-to-noise ratio and a threefold improvement in shutter speed comparedwith those of a single-stage Kerr gate.
