Classification: CPC G  B  Y | IPC B  G

Claim 18:
19. A multi-spectral sensor, comprising:
a splitter configured to split electromagnetic emissions from a thermally-excited material into a first light beam and a second light beam, the first light beam corresponding to line emissions of a component of the material, the second light beam corresponding to continuum emissions of the component of the material;
a first filter configured to receive the first light beam and pass light having wavelengths within a range about the line emissions of the component of the material and block or attenuate light having wavelengths outside the range about the line emissions of the component of the material;
a second filter configured to receive the second light beam and pass light having wavelengths within a range about the continuum emissions of the component of the material and block or attenuate light having wavelengths outside the range about the continuum emissions of the component of the material;
a processor configured to:
generate line data, SLine, representative of an intensity of the first light beam;
generate continuum data, SContinuum , representative of an intensity of the second light beam;
generate a value based on the SLine and SContinuum.
