The Glitter Telescopes

Dick just let me know of the following:

Good catch, thank you Dick !

The NPR piece below mentions computational imagery for reconstructing the image but the papers on Grover Swartzlander publication page (including the one below) do not seem to indicate much in the way of L1 or similar regularization. It's just a question of time. Depending on how much they know about the glittering particles, it might be a compressive sensing or a compressive phase retrieval problem. Time will tell but I love the connection with some of technologies featured in "These Technologies Do Not Exist" page.

We experimentally explored the reconstruction of the image of two point sources using a sequence of random aperture phase masks. The speckled intensity profiles were combined using an improved shift-and-add and multi-frame blind deconvolution to achieve a near diffraction limited image for broadband light (600-670 nm). Using a numerical model we also explored various algorithms in the presence of noise and phase aberration. © (2015) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
