High-speed digital color imaging pyrometry
WebFeb 15, 2024 · Both two-color pyrometry and high-speed thermography were used to monitor the transient temperature of the projectile during and post-impact. The pyrometer monitored the area immediately surrounding the impact site, and measured temperatures close to theoretical adiabatic flame temperatures (Taf). WebJun 23, 2024 · Abstract A simple combination of the Planck blackbody emission law, optical filters, and digital image processing is demonstrated to enable most commercial color cameras (still and video) to be used as an imaging pyrometer for flames and explosions.
