JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]UCLA researchers led by Aydogan Ozcan and Mona Jarrahi have developed a multispectral imaging technology capable of turning a monochrome sensor into a multispectral one. Rather than the traditional absorptive filters used for multispectral imaging, the technology uses a diffractive optical network to form 16 unique spectral bands periodically repeating at the output image field of view to form a virtual multispectral pixel array. Multispectral imaging is used in applications including environmental monitoring, aerospace, defense, and biomedicine. Due to their compact form factor and...Read full articleRelated content from Photonics MediaArticlesMultispectral Terahertz Imaging System Incorporates Neural NetworkResearchers at UCLA have developed a focal plane array (FPA) capable of supporting real-time multispectral terahertz (THz) video in 3D.
