Singleshot Multispectral Imaging via a Chromatic Metalens Array
Romil Audhkhasi, Ningzhi Xie, Johannes E. Fröch +1
Real time, singleshot multispectral imaging systems are crucial for environment monitoring and biomedical imaging. Most singleshot multispectral imagers rely on complex computation…
Computational metaoptics for imaging
Charles Roques-Carmes, Kai Wang, Yuanmu Yang +2
Metasurfaces -- ultrathin structures composed of subwavelength optical elements -- have revolutionized light manipulation by enabling precise control over electromagnetic waves' am…
Broadband long-range thermal imaging via meta-correctors
Cameron Vo, Owen Anderson, Anna Wirth-Singh +3
Long-range imaging in the thermal infrared band is critical for applications such as environmental monitoring, industrial inspections, and surveillance. To achieve high quality ima…
Meta-optical Imaging at Thermal Wavelengths
Anna Wirth-Singh, Aurelia M. Brook, Rose Johnson +2
The field of meta-optics has grown to include metalenses spanning the ultraviolet to terahertz regimes. Imaging is a key application of meta-optics, with recent works demonstrating…
End-to-end metasurface design for temperature imaging via broadband Planck-radiation regression
Sophie Fisher, Gaurav Arya, Arka Majumdar +2
We present a theoretical framework for temperature imaging from long-wavelength infrared thermal radiation (e.g. 8-12 m) through the end-to-end design of a metasurface-optics fr…
2D beam shaping via 1D spatial light modulation
James E. M. Whitehead, Albert Ryou, Shane Colburn +2
Many emerging reconfigurable optical systems are limited by routing complexity when producing dynamic, two-dimensional (2D) electric fields. Using a gradient-based inverse designed…
