Development of hybrid CMOS detectors (HCDs) as X-Ray focal plane instruments could place them in contention with CCDs for future missions due to their faster frame rates, flexible readout geometry, and inherent radiation hardness. In order for HCDs to be useful as X-Ray detectors, they must perform similarly to CCDs while retaining their inherent advantages. Our work characterizes the point spread function (PSF) of a Teledyne X-Ray enhanced HAWAII-H1RG HCD, which shows many multipixel events attributed to interpixel capacitance (Kenter et. al., 2005). We show that deconvolution of the raw images with a Lucy-Richardson algorithm achieves a significant improvement in spatial resolution and X-ray event characterization, without any degradation of the intrinsic detector energy resolution.
