MEMS-based Tunable Infrared Filters: SWIR Multi-spectral Imaging
MEMS spectrometers operating in the shortwave infrared (SWIR) range are achieving significant progress in agriculture by offering portable solutions for soil and crop analysis. Recent innovations focus on extending the actuation range of MEMS tunable optical filters and addressing issues like snap-down with a new floating electrode design. This approach improves stability and expands the wavelength range from 1.25 μm to 1.76 μm. These enhancements ensure the devices perform reliably under various conditions, helping in precise agricultural assessments and better crop management.
