Raw images obtained with helicam C3 in a DPC microscope setup. The raw images were used for the figures in the publication Chiara Bonati, Damien Loterie, Timothé Laforest, Christophe Moser. Lock-in incoherent differential phase contrast imaging. Photonics Research, 2022, 10(1):237. Contents of the data set: Contrast comparison: 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. Lock-in DPC: lock-in DPC image sets. Each image was collected over four cycles of 140 us each. 5_mrad: 5 mrad sample Background: no sample image I: Frame I Q: Frame Q Sample: sample image I: Frame I Q: Frame Q 13dot8_mrad: 13.8 mrad sample 15dot1_mrad: 15.1 mrad sample 18dot9_mrad: 18.9 mrad sample 35dot2_mrad: 35.2 mrad sample 50dot5_mrad: 50.5 mrad sample Standard DPC: Same set of images, under standard DPC conditions. Each illumination (left and right) was recorded for 1 us. 5_mrad: 5 mrad sample Background: no sample image L: Image under left illumination R: Image under right illumination Sample: sample image L: Image under left illumination R: Image under right illumination 13dot8_mrad: 13.8 mrad sample 15dot1_mrad: 15.1 mrad sample 18dot9_mrad: 18.9 mrad sample 35dot2_mrad: 35.2 mrad sample 50dot5_mrad: 50.5 mrad sample Reconstruction: Image sets used for figures 5 and 6 USAF_50dot5mrad: Image sets of a 50.5 mrad glass USAF target. Illumination: Folder containing the back-focal plane characterisation of the imaging system, used to compute the transfer functions for phase reconstruction. BFP: the back-focal plane aperture of the 0.4 NA objective P_1: reduced pupil used in the experiments s_L: left source s_R: right source Lock-in DPC: lock-in DPC image set. The equivalent exposure time was 464 us. Standard DPC: standard DPC image set. Each illumination was exposed for 8 us. Onion: Image sets of onion epidermal cells. Lock-in DPC: lock-in DPC images for varying equivalent exposure times. 104 us 120 us 136 us 152 us 168 us 184 us 200 us 216 us 232 us 248 us Standard DPC: Standard DPC image set at 7 us exposure time
