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…
Computed tomography using meta-optics
Maksym Zhelyeznuyakov, Johannes E. Fröch, Shane Colburn +2
Computer vision tasks require processing large amounts of data to perform image classification, segmentation, and feature extraction. Optical preprocessors can potentially reduce t…
Transferable polychromatic optical encoder for neural networks
Minho Choi, Jinlin Xiang, Anna Wirth-Singh +3
Artificial neural networks (ANNs) have fundamentally transformed the field of computer vision, providing unprecedented performance. However, these ANNs for image processing demand…
