High-resolution multi-spectral imaging with diffractive lenses and learned reconstruction
Spectral imaging is a fundamental diagnostic technique with widespread application.
Conventional spectral imaging approaches have intrinsic limitations on spatial and spectral
resolutions due to the physical components they rely on. To overcome these physical
limitations, in this paper, we develop a novel multi-spectral imaging modality that enables
higher spatial and spectral resolutions. In the developed computational imaging modality,
we exploit a diffractive lens, such as a photon sieve, for both dispersing and focusing the …
