We propose a rigid-scope system that can perform hyperspectral imaging (HSI) between visible to over 1000 nm (OTN) using a supercontinuum light source and an acousto-optic tunable filter to emit specific wavelengths. In this study, the system was developed, and its optical performance verification and classification ability were investigated. Consequently, it was demonstrated that HSI (490–1600 nm) could be performed. In addition, seven different targets could be classified by the neural network with an accuracy of 99.6%, recall of 93.7%, and specificity of 99.1%, when the wavelength range of OTN was extracted from HSI data as train data.
