Yasuo Ohtera, Kazuma Shinoda
A near-infrared (NIR) spectral sensor consisting of a 25-channel dielectric multi-patterned filter array (MFA) and CCD is proposed and fabricated. The MFA consists of a wavy dielectric multilayer with a gradient layer profile on a silica substrate with surface grating. The incoming NIR spectrum is ... [Appl. Opt. 58, 3166-3173 (2019)]
