  Coded apertures, traditionally employed in x-ray astronomy for imaging
celestial objects, are now being adapted for micro-scale applications,
particularly in studying microscopic specimens with synchrotron light
diffraction. In this paper, we focus on micro-coded aperture imaging and its
capacity to accomplish depth-resolved micro-diffraction analysis within
crystalline specimens. We study aperture specifications and scanning parameters
by assessing characteristics like size, thickness, and patterns. Numerical
experiments assist in assessing their impact on reconstruction quality.
Empirical data from a Laue diffraction microscope at a synchrotron undulator
beamline supports our findings. Overall, our results offer key insights for
optimizing aperture design in advancing micro-scale diffraction imaging at
synchrotrons. This study contributes insights to this expanding field and
suggests significant advancements, especially when coupled with the enhanced
flux anticipated from the global upgrades of synchrotron sources.
