Cover Story: A new high-speed infrared thermometer is redefining how we measure combustion. Designed around an InAsSb photodiode and operating across 3 to 11 μm, this non-contact instrument captures the surface temperature of Jet A kerosene droplets with microsecond precision, without disturbing the flame. Sensitive below 300 °C and accurate to within ±2 °C, it reveals transient thermal behaviour that conventional probes often miss. Validated against industry standards, the system offers a robust platform for fuel characterisation under controlled conditions. By enabling time-resolved thermal measurements with minimal interference, this technique supports the development of cleaner, more efficient aviation technologies and provides a valuable tool for advancing combustion diagnostics and sustainable fuel research. View this paper
