Near-infrared hyperspectral imaging (HSI) has attracted significant attention in the food and industrial fields as a non-destructive technique for analyzing the composition of objects. A notable aspect of NIR-HSI is over-thousand-nanometer (OTN) spectroscopy, which can be used for the identification of organic substances, their concentration estimation, and 2D map creation. Further, it is necessary to construct cameras, optical systems, and illumination systems for portable NRI-
