Thus, the study of the energy spectrum of these sources is of paramount importance. In the direct imaging technique, we can estimate the source spectrum by considering the counts in the region illuminated by the source. However, at high energies, indirect imaging methods such as Coded Mask Imaging (CAM) are often used to help cover a large Field of View (FOV). In this poster, we are presenting conventional method used in indirect imaging to reconstruct the spectrum of the source. Also, we will present limitations of the conventional method and propose a new Bayesian-based technique to overcome the limitations of the conventional method. |
