Optimization of LED Illumination for Hyperspectral Imaging Applications

Описание: Hyperspectral imaging (HSI) is transforming industries such as food processing, materials recycling, and pharmaceuticals by enabling high-speed, non-contact identification of product characteristics. From detecting ripeness and bruising in fruit to classifying plastics in recycling and verifying pill formulations, HSI systems provide powerful spectral insight at production-line speeds.

Inline HSI systems typically use a line-scan camera coupled with a wavelength-dispersing element—such as a grating or prism—to acquire detailed spectral data as objects move along a conveyor. The resulting hyperspectral data cube reveals spatial and spectral information across ultraviolet (UV) to mid-infrared (mid-IR) wavelengths, with increasing interest in the shortwave infrared (SWIR) range. A frequently underestimated—but critical—component of system performance is illumination. The light source must deliver high radiant intensity over the relevant spectral range while maintaining exceptional temporal and spectral stability. It must also uniformly illuminate the entire field of view, accommodate diverse object sizes, and minimize shadowing artifacts—challenges that grow with system speed and application complexity.

Whether you are developing new HSI camera systems or integrating spectral imaging into existing automation platforms, this webinar will offer practical insight into achieving better results through optimized, application-specific illumination strategies. Hyperspectral imaging (HSI) is revolutionizing industries such as food processing, materials recycling, and pharmaceuticals by enabling high-speed, noncontact identification of product characteristics. Yet, one of the most underestimated — and absolutely critical — determinants of overall system performance is the illuminator.

This webinar reveals how optimized, performance-driven LED illumination strategies can dramatically improve results, unlock new capabilities, and give your solutions a competitive edge in the marketplace.
