Abstract
Uncooled MWIR imagers are not widely used until now, but offer great potential for various imaging scenarios. Fraunhofer IMS is therefore developing specialized imagers for the MWIR spectral range between 3 – 5 μm. In contrast to quarter-wavelength resonators, which are the established concept for LWIR optimized microbolometers, the integration of plasmonic metamaterial absorbers (PMA) realized by metal-insulator-metal absorbers (MIM) enables uncooled MWIR imaging. PMAs allow for the realization of narrowband MWIR imagers that may be a supplement to the classic broadband infrared imagers based on quarter-wavelength resonators. An overview of both approaches and their application-oriented advantages and disadvantages is given within this paper.
