Hyperspectral imaging system for pyrometry applications and method of operating the same

A method for operating a pyrometry imaging system for monitoring a high-temperature asset which includes at least one component, said method comprising:

• receiving, by a lens element, a portion of thermal radiation emitted from a plurality of thermal points of the at least one component, wherein each thermal point of the plurality of thermal points defines a section of the at least one component;
• transmitting, from the lens element, the portion of thermal radiation emitted through a view limiting device to a dispersive element;
• splitting, by the dispersive element, the portion of thermal radiation emitted into a plurality of wavelength points for each of the received thermal points, wherein each wavelength point of the plurality of wavelength points represents a wavelength of the portion of thermal radiation emitted from the corresponding thermal point;
• transmitting, by the dispersive element, at least some wavelength points of the plurality of wavelength points to at least one camera device;
• and
• generating, at the at least one camera device, a stream signals substantially representative of the plurality of wavelength points corresponding to each thermal point of the plurality of thermal points;
• and
• generating a two-dimensional array based on the stream of signals, wherein a first dimension of the two-dimensional array represents the plurality of thermal points and a second dimension of the two-dimensional array represents the plurality of wavelength points corresponding to a thermal point of the plurality of thermal points.
