A system for providing active real-time characterization of an article under test is disclosed. An infrared light source, a first visible light source and a second visible light source each outputs and directs a beam of coherent light at a particular area on the article under test. A visible light camera and a visible light second harmonic generation camera, an infrared camera and an infrared second harmonic generation camera, a sum frequency camera and a third order camera are each configured to receive a respective predetermined return beam of light from the particular area on the article under test. A processor receives signals from the cameras and calculates in real time respective spectroscopic signals and compares each calculated signal with each other calculated signal and with a predetermined baseline signal to ensure that the article under test conforms to an expected value.
