I didn’t know much that technique beforehand, and that some of the concepts were still in debate. The setup with the spatial light modulator reminds me of holography.
Nice schematics by the way!

Some researchers from Stanford develped what they called “Dual Photography” (http://graphics.stanford.edu/papers/dual_photography/) which is similar to your last example.

In their paper, one example shows them turning the face of a playing card towards a matte surface (a book page), then using a single-pixel camera technique on the diffusely reflected light to reconstruct the hidden card face in great detail. It was pretty impressive looking.
