What is it about?
Ultrasound-modulated optical tomography (UOT) is a technique that combines light and ultrasound with the aim to image deep inside scattering media. A pulsed version of this technique involving holography is proposed and discussed.

Why is it important?
In this work, we describe theoretically the detection of the tagged photon in heterodyne holography based UOT, show how to filter the untagged photon, and discuss the effect of shot noise. The discussion considers also speckle decorrelation.
Perspectives
We show that optimal detection sensitivity can be reached, if the frame exposure time of the camera used to perform the holographic detection have the same order of magnitude of the decorrelation time.
