    Abstract: PROBLEM TO BE SOLVED: To disclose a technique for detecting water vapor in a natural gas background. SOLUTION: This device includes a light source (519) emitting light approximately within wavelength ranges such as 920 to 960 nm, 1.877 to 1.901, or 2.711 to 2.786. The light source emits light which passes through a specimen of natural gas and is detected by a detector (523). In one embodiment, the light source is a tunable diode laser and the moisture level is determined by harmonic spectroscopy. In other embodiments, a VCSEL, a color center laser, or a quantum cascade laser is utilized. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract translation: 要解决的问题：公开一种在天然气背景下检测水蒸气的技术。 解决方案：该装置包括发射大约在920至960nm，1.877至1.901或2.711至2.786的波长范围内的光的光源（519）。 光源发射通过天然气样本的光，并由检测器（523）检测。 在一个实施例中，光源是可调二极管激光器，并且通过谐波光谱确定湿度水平。 在其他实施例中，使用VCSEL，彩色中心激光器或量子级联激光器。 版权所有（C）2011，JPO＆INPIT

    Abstract: A technique is disclosed for the detection of water vapor in a natural gas background. The system includes a light source (519) emitting light approximately within wavelength ranges such as 920- 960 nm, 1.877 - 1.901, or 2.711 - 2.786 . The light source emits light through a sample of natural gas that is detected by a detector (523). In one embodiment, the light source is a tunable diode laser and the moisture level is determined by harmonic spectroscopy. In other embodiments, a VCSEL, a color center laser, or a quantum cascade laser is utilized.
