Table 1. Ablation study evaluating the effectiveness of our partially coherent model.
For the LED and SLED sources, we test our model with an increasing spectral bandwidth ranging from a Dirac delta δλ to 15 nm. The LED is further tested, assuming an infinitesimal small source with area δA and a finite size corresponding to our optical pinhole with a diameter of 75 μm. The PSNR (decibels) values significantly increase for the partially coherent sources when accounting for temporal and spatial incoherence. The SLED achieves the best result overall.
