DoFP Polarimetric Resolution Benchmark (DoFP-PRB)
The DoFP Polarimetric Resolution Benchmark (DoFP-PRB) is an open research benchmark for the characterization and comparison of division-of-focal-plane (DoFP) imaging polarimeters, analyzer modulation architectures, and polarimetric demosaicing algorithms.
DoFP-PRB combines full-resolution polarimetric reference measurements with controlled synthetic DoFP sampling, standardized reconstruction and performance metrics, and measurements from physical DoFP sensors. The benchmark uses polarimetrically structured Siemens-star and zone-plate targets to characterize spatial-polarimetric resolution, aliasing, Stokes-channel isolation, and reconstruction fidelity under a common evaluation framework.
Benchmark releases include polarimetric reference and experimental datasets, MATLAB analysis software, target-design files, and example workflows. The framework supports both the modulation architectures evaluated in the associated publications and user-defined analyzer patterns and demosaicing algorithms.
DoFP-PRB v1.0 is the initial LWIR benchmark release. It provides full-resolution division-of-time (DoT) polarimetric reference measurements, measurements from three physical LWIR DoFP configurations, six analyzer modulation architectures, a common Fourier-domain reconstruction baseline, and standardized spatial-polarimetric characterization tools.
Versioned releases are retained in this repository to support reproducibility of published results and continued expansion of the benchmark.
