Hyperspectral Imaging: Analyzes wavelengths to visualize subtle differences in color, materials, and foreign materials

Hyperspectral imaging is a technology that uses a hyperspectral camera with high wavelength resolution
and corresponding light to acquire images.

By capturing and visualizing the reflected light of an object, it can perform inspections that are dificult to achiever with conventional cameras, such as component analysis, foreign material detection, and high-precision color identification

Challenges to be solved with hyperspectral imaging:

  • Analyze the reflection spectrum of the object
  • Achieve high-precision color identification that is not possible with standard industrial cameras
  • Classify multiple materials, detect foreign materials, and analyze components
