  We exploit memory effect speckle correlations for the imaging of incoherent
linear (single-photon) fluorescent sources behind scattering tissue. While
memory effect-based imaging techniques have been heavily studied in the past,
for thick scattering layers and complex illumination patterns these
correlations are weak, limiting the practice applicability of the idea. In this
work, we introduce a Spatial Light Modulator (SLM) between the tissue sample
and the imaging sensor and capture multiple modulations of the speckle pattern.
We show that by correctly designing the modulation pattern and the
reconstruction algorithm we can greatly enhance statistical correlations in the
data. We exploit this to demonstrate the reconstruction of mega-pixel wide
fluorescent patterns behind scattering tissue.
