| Abstract: Micropore optics (MPO) offers compact, lightweight focusing for wide-field X-ray imaging and spectroscopy, with applications as X-ray sky monitors to detect transients. At the Space Astronomy Group of URSC, we are exploring MPO to build a wide-field X-ray monitor instrument. We characterize MPO imaging performance and present experimental results on point spread function (PSF), imaging capability, effective area, and their energy dependence in the 0.5–4 keV range. The experimental findings are validated through comparative simulations which incorporate non-ideal aspects such as specular scattering, non-monoenergetic incident radiation, and energy-dependent reflectivity to provide realistic predictions. The PSF is experimentally determined and compared with simulations, showing good agreement in spot size and shape. Focal length estimates from both simulations and experiments also agree well. Current efforts focus on off-axis behaviour, energy-dependent effective area of MPO, and refining simulations to support spectral performance studies. The combined experimental and simulation approach forms the basis for optimizing design and developing an MPO-based wide-field X-ray imaging spectrometer. |
