FIELD: physics.
SUBSTANCE: method involves use of a colour RGB camera to record radiation intensity of a reaction product in the red, green and blue wavelength ranges. A chemiluminescence value is generated from the corresponding blue signal of the colour RGB camera. A Planck radiation value is generated from the corresponding red and/or green signals of the colour RGB camera through comparative pyrometry. The radiation intensity value is generated by comparative pyrometry based on the difference between chemiluminescence value and the corresponding Planck radiation value. The apparatus includes a colour RGB camera connected to a processing unit, having means of determining chemiluminescence values from the blue signal of the colour RGB camera and Planck radiation values from the red and/or green signals of the colour RGB camera by comparative pyrometry, and means of determining radiation intensity based on the difference between chemiluminescence and Planck radiation values.
EFFECT: method which reduces complexity and provides high reliability.
