Yongcai Guo, Zhao Chen · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 2006
This paper studies near infrared technology for measuring moisture content in solid substance. After analyzing and improving traditional moisture instruments and discussing their disadvantages, we present a measuring scheme and instrument structure design with high performance and stability. The novel instrument utilizing near infrared range analysis (NIRA) technology possesses characteristics of on-line working, high accuracy, distribution and non-contact measurement.
