The present specification describes a system of acquiring spectral information from backscatter scan data acquired using a detector panel having an array of 'm' spatially distributed, independent detector assemblies or modules an array of ‘n’ filters positioned over the array of detector assemblies or modules. In some embodiments, m=n. From the acquired set of detector response measurements, an energy spectrum is mathematically reconstructed or calculated by formulating and solving the energy reconstruction problem as an inverse problem.
