Complex wavefront engineering via decoupled space-time modulation
Virat Tara, Anna Wirth-Singh, Johannes E. Fröch +1
Solid-state Spatial Light Modulators (SLMs) are fundamentally limited in their ability to achieve high spatial complexity and high temporal bandwidth simultaneously. High-speed, lo…
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…
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 f…
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…
