The background, optical properties, and applications of low-loss negative curvature hollow-core fiber are reviewed. Data on spectral attenuation are collated and extended.
Developing physical methods to detect aflatoxin is a significant area of research in food safety. Because the current detection methods that use near-infrared spectroscopy are not sufficiently accurate, we focus here on using terahertz (THz) spectroscopy to detect aflatoxin B1. We first studied the process of extraction and conservation of aflatoxin B1 from corn. Next, according to the refractive...
Terahertz time-domain spectroscopy has been used to analyze the mixed samples of different mass ratio of L-Tyrosine and L-Phenylalanine. The total dipoles of theses mixtures are given by absorption line shape function. Moreover, the statistical method of principle components analysis is employed to spectral recognition of these samples.
We study spectral attenuation limits in silica hollow core negative curvature fibers. We demonstrate transmission to 4.3 μm wavelength and analyze the attenuation curve. The lowest attenuation measured is 24 dB/km at 2400 nm wavelength.
Technology integrated innovation is realized by integrating the useful features of two or more technologies to improve one technology or create a new product. The method for technology integrated innovation is discussed. Referring to gene recombination, the conception of technology basis recombination is put forward. A design process model for technology integrated innovation based on technology basis...
