NIR Imaging
Daitaro Ishikawa, Mika Ishigaki, and Aoife Ann Gowen
Abstract Visualization of the spatial distribution of surface properties is increasingly desired in many fields. Spectral imaging combines spectroscopy with imaging,
implying images with three dimensions: two spatial and one spectral. NIR spectral
imaging enjoys many of the useful features of NIR spectroscopy such as suitability for
nondestructive measurement, in situ analysis and potential for transmission measurements. NIR imaging systems can provide high-speed monitoring and stability. These
features are very attractive not only for laboratory-based studies but also for applications in a number of practical fields such as pharmaceutical, medical, engineering,
biological and agricultural. NIR imaging technology is still developing by improvement of spectral analysis method; chemometrics and image analysis methods. In this
section, we describe the concept of NIR spectral imaging at first and introduce the
basic design of NIR imaging devices and the features of newly developed devices.
Finally, the potential of NIR imaging for practical situation is demonstrated through
several applications reported at recent years.
