A Short Introduction to Shortwave Infrared (SWIR) Imaging
Occupying the electromagnetic spectrum just above the near-infrared, the shortwave infrared (SWIR) range – between 1,050 and 2,500 nm – lies firmly beyond the reach of conventional silicon-based imaging sensors. Yet despite this, the SWIR band is finding increasing application in machine vision for the unique capabilities it offers for inspection, sorting, and quality control, as well as for ambient light applications such as surveillance and remote sensing.
