Near-IR laser-induced vibrational overtone absorption systems and methods for material detection

Patent image
ARL

Embodiments of present invention are directed to near infrared (IR) laser-induced vibrational absorption systems and methods for material detection. According to one embodiment, a system for detecting materials may include: at least one laser configured to output light in the near IR spectrum so as to excite at least one vibrational overtone frequency, at least one combination band frequency, or a combination thereof, of a sample comprised of one or more of materials; a detector configured to detect a physical phenomenon of the sample in response to laser excitation; and an analyzer configured to the analyze the detected physical phenomenon and to identify the one or more materials based comparison of the detected signatures with known signatures of one more materials.
