Near infrared spectroscopy(NIRS) has distinguished itself as one of the most rapidly advancing analytical techniques over the last few decades.The fundamentals of vibrational spectroscopy
instrumentation and chemometrics are the three main sustaining pillars of modern near infrared spectroscopy analytical technology.In recent years
near infrared spectroscopy technology has made remarkable progresses in these three aspects.In this paper
the latest development of NIR analytical technology and its various applications in these three aspects are summarized
