  An all optical implementation of pulse reconstruction using time-domain
ptychography is demonstrated showing excellent results. Setup and
reconstruction are easy to implement and a number of drawbacks found in other
second order techniques are removed, such as the beam splitter modifying the
pulse under consideration, the time ambiguity, or the strict correspondence
between time delay increment and temporal resolution. Ptychography generally
performs superior to algorithms based on general projections, requires
considerable less computational effort and is much less susceptible to noise.
