We demonstrated high-speed near infrared spectrocsopy of low transmittance samples by using a developed high-power spectrometer (chirped pulse spectrometer). Quantitative spectrum of Intralipos colliodal solutions was observed for only 5 ms due to a high output power from the spectrometer. We also demonstrated high-speed spectroscopy of samples moving at a high speed (3 m/s) as a demonstration of in-line total inspection in food and chemical production lines.
