Broadband GaAsSb Nanowire Array Photodetectors for Filter-Free Multispectral Imaging.
Nano letters (Print), 2021Highly compact, filter-free multispectral photodetectors have important applications in biological imaging, face recognition, and remote sensing. In this work, we demonstrate room-temperature wavelength-selective multipixel photodetectors based on GaAs0 ...

Multispectral Large‐Panel X‐ray Imaging Enabled by Stacked Metal Halide Scintillators
Advances in Materials, 2022Conventional energy‐integration black–white X‐ray imaging lacks the spectral information of X‐ray photons. Although X‐ray spectra (energy) can be distinguished by the photon‐counting technique typically with CdZnTe detectors, it is very challenging to be

Large-aperture linear diffractive axicons are optical devices providing achromatic nondiffracting beams with an extended depth of focus when illuminated by white light sources. Annular apertures introduce chromatic foci separation, making chromatic imaging possible despite important radiometric losses.

Deep multispectral image registration network
Computerized Medical Imaging and Graphics, 2021Multispectral imaging (MSI) of the ocular fundus provides a sequence of narrow-band images to show the different depths in the retina and choroid. One challenge in analyzing MSI images comes from the image-to-image spatial misalignment, which occurs because the acquisition time of eye MSI images is commonly longer than the natural time scale of the eye'

The shortcomings of the conventional three-channel imaging are rooted in metamerism problems. To avoid these problems multispectral imaging is introduced as an complementary approach. This imaging technology uses the complete spectral information of the original image, and, hence, avoids the problems due to metamerism.
