asteroza + holographic   22

Wearable MRI
Using sound somehow to redirect infrared light to allow internal imaging like an MRI. Uses some sort of holographic imaging technique.

I think this uses some sort of holographic mirror lens assembly, considering one of the optics developers worked on aviation helmet display systems?

Re-Envisioning the Telescope
Interesting way of making huge primary telescopes, using holographic sheet diffraction ratings, suitable for space telescopes. I wonder if the reverse works, shining a high power laser back out the scope to achieve a wide aperture primary.

Optics InfoBase: Biomedical Optics Express - Field-portable reflection and transmission microscopy based on lensless holography
Idea is to use a cheap laser, holographic lensing, a cheap smartphone camera sensor, combine into a simple microscope, and offload raw image processing to a smartphone or even a cloud service.
