Spectral Sensing Using a Handheld NIR Module Based on a Fully Integrated Sensor Chip
November 01, 2022
A novel approach to NIR spectral sensing, using a miniaturized fully-integrated multipixel array of resonant-cavity-enhanced InGaAs photodetectors,
enables sensors with a millimeter-scale footprint and wafer-scale fabrication.
This multipixel sensor does not measure the full spectrum, but rather a limited number of spectral regions with limited resolution (50–100 nm).
