Development of 490–1600 nm hyperspectral imaging system based on flexible fiberscope
Herein, we report on a flexible fiberscope system that can perform hyperspectral imaging (HSI) from 490-1600 nm. The spectroscopy method uses a supercontinuum light source and an acousto-optic tunable filter to output a specific wavelength at 6 nm intervals. The HSIs of the six resin samples were obtained and classified using a neural network under four wavelength ranges. The highest performance was achieved for the 1000-1600 nm range, with accuracy of 99.0%, recall of 94.6%, and specificity of 98.8%. The proposed system has potential applications in the medical and industrial fields for noninvasive component analysis.
