“…In a previous conference paper, we detailed our attempts to implement an energy dependent version of EI that could take advantage of the emergence of energy sensitive detectors. 2 This method would allow us to collect data for multiple energy measurements simultaneously instead of several spatial shifts separately, thereby simplifying the system and lowering the data collection time.…”

As opposed to transmission imaging, X-ray Phase Contrast Imaging (XPCI) produces images with higher contrast and allows us to distinguish between materials that are weakly attenuating or between materials that possess similar attenuation values. Edge Illumination (EI), a type of XPCI, utilizes spatial variation to uncover information about an object's phase properties, such as the index of refraction. Instead of spatial variation, we previously proposed an alternative EI method, Spectrally Responsive Edge Illumination (SREI), which relies on energy variation. Prior SREI experimental efforts struggled to meet the necessary component performance requirements, so, as an intermediate step, we are currently focused on developing an energy resolving X-ray refractometer and a related database of materials. In this paper we will share our theory and initial proof of concept experimental results, as well as our next steps.

X-ray Phase Contrast Imaging (XPCI) is an imaging method used to retrieve phase information from an object, thereby revealing more object characteristics, such as refractive index and thickness. Edge Illumination (EI) is a non-interferometric type of XPCI that is spatially dependent. We developed and simulated an alternative type of EI known as Spectrally Responsive Edge Illumination (SREI), which is energy dependent and utilizes an energy-resolving detector. SREI is intended to be more easily implementable than EI due to fewer precision limitations. We will detail results of our SREI experimental investigation and our plan going forward.
