Hyperspectral Imaging and Applications

Hyperspectral imaging continues to be one of the fast-moving areas of photonics with new advances in instrumentation and the continuous growth in image processing including machine learning and artificial intelligence. Spectral cameras are available in contrasting form factors from space-borne satellite installations to miniature MEMS-based sensors integrated into mobile phones. The breadth and range of applications also continues to grow. Hyperspectral and multispectral cameras are increasingly used on UAV platforms for agricultural and geological surveys. Similar spectral cameras are gaining increased application in industrial scenarios such as sorting, grading and quality control. Newer snapshot cameras provide video rate spectral imaging offering advantages in applications monitoring dynamic scenes such as in some medical imaging.

It can be a challenge to determine the advantages of the differing spectral imaging techniques for specific applications. Also, to determine when it’s best to use multispectral or hyperspectral approaches or the optimum way to process image data. The SPIE Hyperspectral Imaging 2022 conference covers all aspects of hyperspectral imaging and applications and aims to help address some of these questions. Researchers, application engineers, manufacturers and users in industry are all invited to submit papers and participate the event.
