Back Projection Algorithm

 

                                   

Back projection basically projects each detected photon back from the detector through the slits of the grid pairs to all possible locations for its origin on the Sun. This creates a probability map made up of parallel ridges aligned with the slit orientation at that time. The spacing between ridges is equal to twice the FWHM resolution of the subcollimator. This back projection is repeated for each detected photon and the resulting probability maps are summed to form the so-called dirty map.
