AbstractIn the last few years a number of excellent deconvolution algorithms have been developed for use in "de-blurring" 2D images. Here we report briefly on one such algorithm we have studied which uses the non-negativity constraint to optimize the regularization and which is applied to the 2D image like data produced in Coincidence Doppler Broadening Spectroscopy (CDBS). The system instrumental resolution functions are obtained using the 514keV line from 85Sr. The technique when applied to a series of well annealed polycrystalline metals gives two photon momentum data on a quality comparable to that obtainable using ID Angular Correlation of Annihilation Radiation (ACAR).
