The addition of spectroscopy to machine vision systems makes them even more effective. While a combination of machine learning analysis and visible light cameras can be used to inspect defects or check size tolerances in a manufacturing process, spectroscopic methods provide new dimensions of information for quality control and product performance assessment.

In a Raman spectroscopy experiment, a sample is irradiated with a given wavelength of light and the intensity and energy of the inelastically scattered radiation are measured. The energy difference between the incident radiation and scattered radiation gives information about the energy levels in the system.

Thermal imaging technology has dramatically reduced in cost since the mid-2000s, enabling its use in a wide variety of settings. A critical area that cheaper thermal imaging has impacted is wildlife conservation. Here, it can enable wide-reaching, impactful surveys and ongoing, passive monitoring at a fraction of the cost of other methods.

Most industrial manufacturing processes depend on accurately knowing product particle sizes for quality control. Particle size analysis images and characterizes the shape and size of particles in materials. Manufacturing industries conduct particle analysis to ensure that the products meet the standards required to maintain product quality and consistency.
