Lock-in and Standard DPC raw images associated to publication 10.1364/PRJ.445896

<p>Raw images obtained with helicam C3 in a DPC microscope setup. The raw images were used for the figures in the publication Chiara Bonati,&nbsp;Damien Loterie,&nbsp;Timoth&eacute; Laforest,&nbsp;Christophe Moser. Lock-in incoherent differential phase contrast imaging. Photonics Research, 2022, 10(1):237.</p> <p>Contents of the data set:</p> <ol> <li><strong>Contrast comparison</strong>: images used for Figure 4. Several USAF targets of different height, introducing varying phase differences. Samples were imaged under both standard and lock-in DPC. <ol> <li><strong>Lock-in DPC</strong>: lock-in DPC image sets.
