Compound-eye optics enable a simple and scalable 2D scanner to observe more than 2D optical signals without sacrificing spatial or temporal resolution.
A new method of high-resolution computational holography has been developed and experimentally demonstrated.
Micro-structures provide unique identifiers for physical objects, and since they can be optically detected with a mobile device, they can be applied in fields from security and forensics to anti-counterfeiting.
A meta-hologram consisting of sub-wavelength gold cross nanoantennas enables polarization-controlled dual images in the visible region.
A hybrid patterning system combining projection and interference lithography enables the fabrication of 14-inch 3D images.
