As long as the X-ray source can generate sufficiently high energy photons to excite or ionize the core electrons in an element of interest, X-ray fluorescence can be used to measure any element. This is advantageous for robotics applications in mining and geology, where it may be desirable for the robot to detect the presence of previously unexpected elements.

Camera sensors are light-sensitive detectors that convert the incident photons into an electrical signal that can be read out by a digital device. Most cameras make use of 2D array detectors and choosing the right sensor type for a given application is often a trade-off between cost, desired final image resolution and the necessary read-out speed.

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.
