This dataset contains 2 sets of measurements of a 3d-printed microphantom, carried out with optical diffraction tomography system at Warsaw University of Technology. The measurements are conducted for 2 different wavelengths: 633nm and 835nm. Also, tomographic reconstructions of these datasets are shown. The reconstructions were computed with 3 algorithms: GPSC [1], MSBP-I [2] and MSBP-E [3]. Additionally, model of the 3D-printed microphantom is given. All files are *.mat files. In the reconstruction files there are 4 variables: REC - reconstruction matrix with information about 3D refractive index values in the microphantom dx - sample size in the reconstruction in x-y direction dz - sample size in the reconstruction in z direction (if not given, dz=dx) niter - number of iterations that were computed to generate the reconstruction The variables in the sinogram files are: dx - sample size in tomographic projections lambda - wavelength M - magnification in the optical system n_immersion - refractive index of the immersion medium NA - numerical aperture of the optical system rayXY - x-y coordinates of vectors representing illumination directions from which tomographic projections were acquired SINOamp - amplitude distribution of tomographic projections SINOph - phase distributions of tomographic projections The variables in the phantom model files are: dx - sample size n_immersion - refractive index of simulated immersion n_phantom - refractive index of the phantom model [1] W.
