Snapshot multispectral endomicroscopy

Optics Letters, 2020
Multispectral endomicroscopy provides tissue functional information in addition to structural information for accurate disease diagnosis. In this Letter, we propose a snapshot multispectral endomicroscope that employs a fiber bundle to deliver an in-body tissue spatial–spectral datastream to an external compressive spectral imager. Equipped with an end-

Multispectral UV Imaging on Capacitive CMOS Arrays Enabled by Solution-Processed Metal-Oxide Nanoparticles. [PDF]

Adv Sci (Weinh)
Ultraviolet (UV) imagers are important for a variety of applications but often require dedicated semiconductor process flows. Here, a versatile capacitive CMOS platform is transformed into a visible‐blind, multispectral UV imager through post‐CMOS functionalization with solution‐processed metal‐oxide nanoparticles. The UV‐induced photodielectric effect

Multispectral metamaterial absorber [PDF]

Optics Letters, 2014
We present the simulation, implementation, and measurement of a multispectral metamaterial absorber (MSMMA) and show that we can realize a simple absorber structure that operates in the mid-IR and terahertz (THz) bands. By embedding an IR metamaterial absorber layer into a standard THz metamaterial absorber stack, a narrowband resonance is induced at a

Multispectral images of peach related to firmness and maturity at harvest [PDF]

, 2009
wo multispectral maturity classifications for red soft-flesh peaches (‘Kingcrest’, ‘Rubyrich’ and ‘Richlady’ n = 260) are proposed and compared based on R (red) and R/IR (red divided by infrared) images obtained with a three CCD camera (800 nm, 675 nm ...

Research on the light-field characteristics of patterned planar nanotip metasurface [PDF]

EPJ Web of Conferences
Metasurfaces in namo-meter are widely applied to improve the lightwave controllability. The reflection of the proposed planar nanotip metasurface in infrared regime was demonstrated to be effectively modulated, and the minimum value is ~41.0% under an ...
