Abstract

The Tabanidae has a unique eye structure that structural color filter in cornea display advantages for color vision system. The combination of color filter layers and ommatidia can provide the advantages of miniaturization, and multispectral imaging. We report an ultrathin multi-spectral camera inspired by the structure of Tabanidae vision system. The ultrathin multi-spectral camera consists of Fabry-Perot color filter arrays, microlens arrays with chrome aperture, and a CMOS image sensor. The fully packaged camera shows a FWHM under 31nm, a total track length of 1mm. This provides new opportunity for point-of-care testing (POCT) and medical applications.
