Salt grain size cameras

By Molly Sharlach

Salt grain size cameras have great potential to spot problems in the human body and enable sensing for super-small robots. Enabled by a joint design of the camera’s hardware and computational processing.

While a traditional camera uses a series of curved glass or plastic lenses to bend light rays into focus, the new optical system relies on a technology called a metasurface, which can be produced much like a computer chip.

The work was supported in part by the National Science Foundation, the U.S. Department of Defense, the UW Reality Lab, Facebook, Google, Futurewei Technologies, and Amazon.
