Paper Abstract

G9211 series InGaAs linear image sensors are developed by Hamamatsu Photonics, and its spectral response range is 900~1700 nm which is in the range of near infrared spectroscopy. This paper introduces a near infrared spectroscopy data collection system based on G9201 and Nios II, which is the 2nd generation soft IP CPU provided by Altera Corporation. With the help of DspBuilder, which is provided by Altera, the system can analyze the data in real-time with high efficiency. The system's communication is held USB1.1 and TCP/IP protocols. The collection and analysis of samples of the near infrared spectroscopy data on embedded system is implemented on this system as is needed to develop a compact and intelligent NIR spectrometer.
