Appl Opt. 2016 Jul 1;55(19):5008-13. doi: 10.1364/AO.55.005008.

Abstract

An all-optical implementation of pulse reconstruction using time-domain ptychography has been demonstrated showing excellent results. The implementation was easy to set up and eliminated a number of drawbacks found in other second-order techniques, 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 offers superior performance compared to algorithms based on general projections, requires considerably less computational effort, and is much less susceptible to noise.
