Abstract:
By combining spatial and spectral information, hyperspectral imaging enables a unique non-destructive analytical method that allows researchers to identify patterns and trends that would be difficult or impossible to detect using conventional imaging methods alone. Hyperspectral (HS) imaging technology has made its way from satellite instruments used for remote sensing to ground-based and laboratory applications in many fields, including agriculture, environmental and conservation research, food and quality inspection, medicine and biotechnology. HS cameras, capable of capturing spatial and spectral information simultaneously, require a sophisticated optical system design that combines precision optics and image processing techniques. The standard commercially available systems offer a 1 nm spectral resolution for the visible spectral range. In some user cases, one wants to achieve even higher spectral resolution to detect fine spectral nuances. In our work, we present the current developed system and new optical design, which opens the way to better spectral resolution and imaging fidelity.
