Hyperspectral imaging is used to help capture the finest possible differences in materials. Temporal multiplexing is an alternative approach that uses a fast LED technology. Instead of illuminating broadband an splitting the spectrum of light in the camera, a broadband sensitive chip is used, and the illumination spectrum is varied over time via fast triggering. To learn more about how SWIR temporal multiplexing is a cost-effective multispectral solution, download the application note.
