Application of Hyperspectral Imaging for Nondestructive Measurement

Dear Colleagues,

Hyperspectral imaging technology has recently emerged as a powerful analytical technique that uses vibrational spectroscopy for nondestructive quality measurement of various materials. The previously described spectroscopic analytical methods (Vis/NIR, MIR, Fluorescence, Raman spectroscopies, etc.) are well-established, non-invasive analytical techniques for the analysis of materials. However, these techniques are point-based scanning techniques and only examine a relatively small area of a specimen; thus, these techniques are unable to provide spatial information that is important for many material inspection applications. Sample analysis is also more convenient and fast compared with the hyperspectral imaging technique because a large number of samples are analyzed at the same time, instead of the single sampling technique used by the other spectroscopic methods. Furthermore, HSI has instrumental flexibility and can be used to collect hyperspectral data for specimens with different sizes and shapes. In addition, the spectral region collected, spatial resolution, and field of view (FOV) can be adjusted depending on the application. With these advantages and flexibility, hyperspectral imaging has been successfully adopted in a variety of research and industry environments.

This Special Issue focuses on the latest research and development of hyperspectral imaging in nondestructive measurement applications. Accordingly, papers that demonstrate novel hyperspectral imaging technology concepts for nondestructive measurement are sought. These include papers dealing with theoretical analyses, and laboratory and field studies in various industries, such as agriculture, foods, pharmaceutics, natural science, etc.

We would like to invite you to submit original research papers for the “Application of Hyperspectral Imaging for Nondestructive Measurement” Special Issue.
