We demonstrate a multi-aperture longwave-infrared multispectral imaging technique that, though simple, uniquely combines for the first time the advantages of high throughput, video-rate operation, real-time optimization and low cost. We report snapshot imaging, detection and classification of gas clouds and plastics.

We present methods to design optical elements using optimization. As a demonstration, we fabricate silicon metagratings that can split and bend light with record efficiencies. We envision that meta-optics will enable new modalities in imaging.

Identifying ambiguities and high stress regions in digital photoelasticity is a complex process. We consider such zones as salient information, and process them through saliency algorithms. Hence, highlighted information coincided with ambiguities and stress concentrations.

A phase-resolved heterodyne shearographic vibrometer is under development for observations of transient surface motion. The sensor utilizes frequency and polarization multiplexing with two temporal carrier frequencies to separate each segment of a shearing Mach-Zehnder interferometer.
