WebA simple method for designing and calculating grating optical filters with angular-selective light transmission is presented. The selectivity is provided by the relative positions of two surface gratings formed by directionally transmissive strips, alternating with absorptive, reflective, or scattering strips. As the incidence angle changes, the proportion of radiation … WebJun 24, 2024 · The need for affordable low-power devices has led MEMS-based thermal emitters to become an interesting option for optical gas sensors. Since these emitters have a low thermal mass, they can be easily modulated and combined with a lock-in amplifier for detection. In this paper, we show that the signal measured by a lock-in amplifier from a …
