Automatic identification and sorting of livestock organs in the meat processing industry could reduce costs and improve efficiency. Two hyperspectral sensors encompassing the visible (400–900 nm) and short-wave infrared (900–1700 nm) spectra were used to

Ultralow loss visible light metamaterials assembled by metaclusters
Optical metamaterials give birth to the control and regulation of light. However, because of strong energy dissipation and fabrication difficulty in meta-atoms, low-loss isotropic three dimensional negative index metamaterials (NIMs) in the visible ...

Visible absorption spectrum of liquid ethylene [PDF]
The visible absorption spectrum of liquid ethylene at ≈ 108 K from 5500 Å to 7200 Å was measured by using a pulsed tunable dye laser, immersed-transducer, gated-detection opto-acoustic spectroscopy technique. The absorption features show the strongest band with an absorption coefficient of ≈2 × 10 -2 cm -

State of the Art and Elucidation of Postharvest LED Lighting on the Metabolism of Brassica Sprouts
Brassicaceae sprouts are important sources of vitamins, phenolic compounds, minerals, glucosinolates, and isothiocyanates. LEDs illumination have been demonstrated to increase yield and the phytochemical content of young plants.

Extension of the Visible Spectrum [PDF]
WHILE engaged on work in connection with the discharge of electrification by ultra-violet light, we have come across a fact which it may be convenient to state by itself, viz. that the spectrum of an arc can be made visible over the greater part of its immense range of action on electrified metals, by receiving it upon a screen of the double fluoride ...

This module develops the understanding that visible light is composed of a spectrum of colors of light from red to violet, extends the concept of a spectrum to include non-visible light through discovery, and develops tools and strategies for student ...

Fourier transform infrared spectrometer for a single aerosol particle [PDF]
A spectrometer is reported here for obtaining the infrared spectrum of a single aqueous aerosol particle by a Fourier transform technique. The particle is held in an electrodynamic balance and irradiated simultaneously by the infrared output from a ...

Deep Perceptual Mapping for Thermal to Visible Face Recognition [PDF]
Cross modal face matching between the thermal and visible spectrum is a much de- sired capability for night-time surveillance and security applications. Due to a very large modality gap, thermal-to-visible face recognition is one of the most challenging ...
