摘要： An integrated spectrometer instrument, including an optical source formed on a chip, the optical source configured to generate an incident optical beam upon a sample to be measured. Collection optics formed on the chip are configured to receive a scattered optical beam from the sample, and filtering optics formed on the chip are configured to remove elastically scattered light from the scattered optical beam at a wavelength corresponding to the optical source. A tunable filter formed on the chip is configured to pass selected wavelengths of the scattered optical beam, and a photo detector device formed on the chip is configured to generate an output signal corresponding to the intensity of photons passed through the tunable filter.

摘要： Determination of steam quality by passing one or more laser beams through steam in a steam chamber and directly determining a total number of vapor molecules and a total number of water molecules based on absorption of radiation in the one or more laser beams by the water vapor phase and the liquid water phase in the steam. Specific volumes of water vapor phase and liquid water phase in the steam using the total numbers of water vapor and liquid water molecules are determined and the quality of the steam is calculated based on the specific volumes of the water vapor phase and the liquid water phase in steam. One embodiment comprises a narrow linewidth laser for measuring steam quality and another embodiment comprises multiple broadband lasers for measuring steam quality.
