Dual source BLT reconstructions when the real source central positions is at (–3.0,0.0,0.0) and (3.0,0.0,0.0). Figures (a), (b) and (c) are the corresponding reconstructed results without regularization and with l2 and l1 methods when 106 photons are tracked at 600nm. Figures (d), (e) and (f) are the counterparts corresponding to (a), (b) and (c) when 104 photons are tracked at 600nm.
