Abstract
This dataset accompanies the study demonstrating Super-Resolution Imaging via Photon Enumeration (S-RIPE), a passive optical imaging approach designed to surpass the Abbe-Rayleigh diffraction limit. The S-RIPE method achieves quantum-limited spatial resolution by supplementing spatial intensity data with photon-number distributions measured with a commercial PNR camera.
This repository provides the experimental imaging data, photon-number distributions, and numerical results used to validate the S-RIPE method.
These files provide the empirical basis for utilizing photon enumeration as a robust, alignment-free tool for super-resolution. Researchers can reuse this data to reproduce the study's findings, benchmark alternative passive localization algorithms, or further investigate the role of photon-number distributions in quantum-limited imaging systems.

Description of the data and file structure
Files contain data used to plot the figures in the manuscript "Super-Resolution Imaging via Photon Enumeration". Details describing the data can be found in the manuscript.
Files and variables
Files in FigData.zip:
Fig1columnPND.mat
Photon Number Distributions (probability as a function of number of detected photons) measured in a single column of pixels and shown in Fig. 1 as an example.
Fig2a3Ddata.mat
Photon Number Distributions (probability as a function of number of detected photons) measured for 3 thermal sources for 128 x 128 pixels of the PNR camera.
Fig2aIntMap.mat
Intensity map (mean number of photons measured in each pixel) calculated from the PNR data Fig2a3Ddata.mat and shown in Fig. 5(a) of the revised manuscript.
Fig2b.mat, Fig2c.mat, Fig2d.mat, Fig2e.mat
Photon Number Distributions (probability as a function of number of detected photons) measured for 3 thermal sources and plotted in Figs. 5 (b)-(e). Each file contains a PND for the pixel marked in Fig. 5(a) of the manuscript.
Fig3a.mat
Single-parameter estimation (RMSE of distance between two sources $\delta_x$ with known photon fluxes and known centroid normalized by point spread function (PSF) width) for the distance between two sources set to zero ($\delta_x=0$). 4 cases: balanced S-RIPE, balanced DI, unbalanced S-RIPE, unbalanced DI.
Fig3b.mat
Multi-parameter estimation (RMSE of positions of both sources $\{x_1,x_2\}$ and both photon fluxes $\{\mu_1,\mu_2\}$, $\mu_1\neq\mu_2$, for zero and non-zero separation of the sources normalized by PSF width). In the case of zero separation, DI fails to converge because in the case of zero separation, there is no difference between intensity distributions produced by a single source (i.e.\ $\mu_1 = 0$ or $\mu_2 = 0$) and a pair of sources with any arbitrary photon flux such that the total photon flux is equal to the photon flux of the single light source, while S-RIPE demonstrates performance similar to the single-parameter problem. In the case of non-zero separation, both methods demonstrate near-optimal scaling.
Fig4b.mat
Root mean square error (RMSE) of the S-RIPE technique applied to the experimental data for five thermal sources normalized by PSF width in comparison to simulations for S-RIPE and direct imaging as a function of the separation between the sources normalized by PSF width.
Fig5aIntMap.mat
Raw measured intensity distribution (mean number of photons measured in each pixel) for five thermal sources separated by $\delta_x<\sigma_\text{PSF}$.
Fig5bIntMap.mat
The intensity distribution (mean number of photons measured in each pixel) where raw data from Fig5aIntMap.mat was binned and averaged in 8x8 pixel groups
Fig5c.mat
Positions (pixel coordinates) and intensities (mean number of photons) of the sources extracted with S-RIPE from the raw data
Fig5d.mat
Positions (pixel coordinates) and intensities (mean number of photons) of the sources extracted with S-RIPE from the 8x8 binned data
