Design of a System for Near-Infrared Composite Spectral Image Acquisition and Information Processing

The NIR camera is a device that captures images within the near-infrared spectral range, typically operating wavelengths from 700nm to 2500nm. The camera can possess exceptional penetrating capability and achieve multi-functions, making it a prominent subject of research and application in the industrial sector. The paper provides the system for near-infrared composite spectral image acquisition and information processing which is based on the Alvium 1800 U-130 VSWIR camera by Allied Vision. The system leverages QT Creator to establish an efficient and robust software platform with a user-friendly interface, facilitating NIR image acquisition and information processing across wavelengths ranging from 400 nm to 1700 nm. It is also equipped with narrow band filters for 940 nm, 1450 nm, and 1550 nm. The system effectively tackles challenges regarding the prevention of illegal copying, counterfeiting and infringement areas, detection of water content, differentiation of similar objects, and penetrability. Moreover, it offers practical applications in areas such as anti-counterfeiting measures, food safety assurance, and industrial processes.
