We have developed the composition imaging system with a near infrared (NIR) spectrographic camera. This camera incorporates a sensitive sensor that can detect the distinctive absorption spectra reflected or absorbed by organic substances in the wide wavelength band of 1,000-2,350 nm. The camera can process hyper-spectral data of 320 x 256 pixels at the frame rate of 100-320 fps, and thus enables precise real-time imaging. The composition imaging system is expected to be used for the non-destructive inspection of food and pharmaceutical products for their quality control and evaluation. This paper outlines the NIR spectroscopic camera and presents actual examples of image processing.
