Title: X-ray fluorescence combined with laser induced photon spectroscopy

Abstract: A device and method for identifying the composition of a target sample. The target sample may be a matrix such as a metal alloy, a soil sample, or a work of art. The device includes an x-ray fluorescence detector that produces an x-ray signal output in response to the target sample. The device also includes an optical spectroscope that produces an optical signal output in response to the target sample. Further, a processor is included that analyzes and combines the x-ray signal output and the optical signal output to determine the composition of the test material. In one embodiment, the optical spectroscope is a laser induced photon fluorescence detector.
