Multispectral Sensor with Hybrid Plasmonic CFA

University of Melbourne and Australian National Fabrication Facility publish AIP paper "A single sensor based multispectral imaging camera using a narrow spectral band color mosaic integrated on the monochrome CMOS image sensor" by Xin He, Yajing Liu, Kumar Ganesan, Arman Ahnood, Paul Beckett, Fatima Eftekhari, Dan Smith, Md Hemayet Uddin, Efstratios Skafidas, Ampalavanapillai Nirmalathas, and Ranjith Rajasekharan Unnithan.

"We demonstrate a single sensor based three band multispectral camera using a narrow spectral band red–green–blue color mosaic in a Bayer pattern integrated on a monochrome CMOS sensor. The narrow band color mosaic is made of a hybrid combination of plasmonic color filters and a heterostructured dielectric multilayer. The demonstrated camera technology has reduced cost, weight, size, and power by almost n times (where n is the number of bands) compared to a conventional multispectral camera."
