A holistic view of fireballs: infrared spectroscopy facilitates the acquisition of continuous chemical data from explosions
Jonathan James | | Quick Read
Researchers have developed a novel method to study explosions using infrared spectroscopy. Specifically, broadband Swept-wavelength external cavity quantum cascade laser (swept-ECQCL) spectroscopy allows the acquisition of absorption spectra for chemical products produced within explosive fireballs – with the impressive sampling rate of 500 kHz (1).
Directing a laser generated by the swept-ECQCL device through the fireball, the team were able to monitor changes in chemical composition over the first 10 ms post-explosion. Beyond that initial period – and up to the 100 second mark, the team used broadband high-resolution absorption spectra acquired over the spectral range of 2050–2300 cm−1 at a 100 Hz rate.
