<p>A method of monitoring a high-temperature thermal process, comprising: recording a sequence of images by means of a camera (103) operatively receiving light signals via an optical system; and performing image processing to determine the spatial expanse of a combustion zone and communicating a control signal indicative of the spatial expanse to a system controlling the high-temperature thermal process; wherein the apparatus has a predominant response to light in the wavelength range between 600 nm and 1400 nm; and wherein the image processing involves temporal filtering that enhances relatively slowly varying intensities and attenuates relatively rapidly varying fluctuations. An apparatus (100) for recording such a sequence of images comprises an endoscope (109) for inspection through a hole in a wall of a chamber wherein the process takes place.</p> |
