Abstract
A three-color pyrometer has been developed based on plenoptic imaging technology. Three bandpass filters placed in front of the camera lens allows separate 2D images to be obtained at three different wavelengths. Images were obtained of different black- or grey-bodies including a calibration furnace, a radiation heater, a sooting butane flame and a luminous sulfur match flame. The images were processed to determine 2D temperature distributions. Calibration results in the furnace showed that the instrument could measure temperature with an accuracy and precision of 10 Kelvins between 1100 and 1350 K. Time-resolved 2D measurements of the radiation heater, flame and match are shown.
