Tunable optical filter of porous silicon as key component for a MEMS spectrometer
Philippe Renaud, Sandra Schweizer, Gerhard Lammel
We present a microspectrometer based on a tunable interference filter for infrared or visible light that scans the desired part of the spectrum within milliseconds. A single pixel detector measures serially the intensity at selected wavelengths. This conce ...
2002MEMS infrared gas spectrometer based on a porous silicon tunable filter
Philippe Renaud, Sandra Schweizer, Gerhard Lammel
We present a MEMS infrared spectrometer for selective and quantitative chemical gas analysis. infrared absorption spectroscopy can distinguish gases easily and also detect nonreactive molecules like CO2, in contrast to e.g. metal oxide gas sensors The foll ...
