We summarise 2D imaging solutions fielded at the NIF (pinhole array), MJOLNIR dense plasma focus (coded aperture with scatter and partial attenuation), and DT filled hahlraum experiments (occluded spindle) which all could be fielded at other facilities, such as the Z machine at Sandia. This presents the need-case for a thick imaging aperture reconstruction algorithm (TIARA) code suite to yield comparative metrics for possible aperture designs, which can be used to quantitatively select an aperture for a given use-case. We discuss how the TIARA suite will be used to compare aperture designs and reconstruction methods for an array of use-cases, the current progress of the code suite, and highlight future work that will utilise this code suite.
