28 Μαΐ 2024 · Flat optics enable light manipulation at the subwavelength scale and provide a compact, wave-based, information processing and acquisition platform.
16 Μαρ 2022 · Phase-coded spectral imaging formulates the image generation as a convolution process between wavelength specified point spread function (PSF) and monochrome object image at each wavelength.
In this paper, we review recent progress in the emerging field of computing metasurfaces for all-optical image processing, focusing on innovative and promising applications in optical analog operations, image processing, microscopy imaging, and quantum imaging.
22 Μαρ 2019 · At the same time, wavelength and bandwidth transparency make all-optical signal processing insensitive to signal bandwidth based on the characteristics of flexible spectrum grid in the FON and can process signals at any wavelength without spectral shifting.
19 Οκτ 2020 · With the development of nanofabrication technologies, metasurfaces have shown great potential in manipulating the amplitude, phase, polarization, frequency or simultaneously multiple parameters of output light in ultrashort distance with subwavelength resolution by tailoring the scattering behaviour of consisted nanostructures.
12 Δεκ 2019 · Inspired by the recent progress of convolutional neural network (CNN), we propose iWave as a framework for deriving wavelet-like transform that is more suitable for natural image compression. iWave adopts an update-first lifting scheme, where the prediction filter is a trained CNN, to achieve wavelet-like transform.
