Coherence-gated wave-front sensing in strongly scattering samples

Opt Lett. 2004 Oct 1;29(19):2255-7. doi: 10.1364/ol.29.002255.


We show that, by coherence-gate rejection of out-of-focus light, wave-front distortions can be measured in the presence of a scattering background that is dominant by several orders of magnitude. Applications are expected for multiphoton and confocal laser-scanning microscopy.
