Abstract:
A fiber optic probe system comprising:a fiber optic probe for measuring steam quality,a source of light having a broad wavelength range,a probe tip having a scattering volume defined by a collimating lens and a reflector,a first fiber optic cable for delivering light from said source of light to said collimating lens whereby collimated light travels through said volume and is reflected back to said collimating lens,a second fiber optic cable for receiving the reflected light focused by said collimating lens,a diffraction grating for receiving reflected light from said second fiber optic cable and breaking it into a plurality of spectral lines,a photodiode array for receiving said spectral lines and providing an electrical output signal representative of the intensity of the light at each of said spectral lines,a computer, andan interface module for applying control signals from said computer to said source of light and for applying the output signals from said photodiode array to said computer.
