"Traditional masks are passive," said co-first author Cheng-Yu Wang, doctoral candidate in electrical engineering. "We can add functionalization to our microwire, like polarization, selectivity and plasmonic effects, that make our imaging system more powerful."

In the case of cellphones, one major contributor to their bulk is due to the camera lens needing to be a certain distance to the detector. A lensless camera could help minimize the space requirement. Likewise, a lens-free system added to a cellphone could turn the cellphone into a low-power microscope.

Along with Miller and Yang, senior authors on the ACS Nano paper, "Particle-based reconfigurable scattering masks for lensless imaging," are Christine Keating, distinguished professor of chemistry, and Zhiwen Liu, professor of electrical engineering.
