摘要： The invention relates to a mobile remote detection device for accumulations of methane, comprising an emitter device having a light source in order to generate light, the wavelength of said light source being tuned with the spectral signature of methane, whereby the light can be directed onto a measuring field. The detection device also comprises a detector device for detecting backscattered light, and an evaluation device. The aim of the invention is to improve the remote detection device in such a manner that it has a high degree of measuring sensitivity with a compact and stable structure. According to the invention, the light source generates light with a wavelength at which methane is absorbed, wherein the wavelength lies between 3200 nm and 3300 nm, and the light source has an optical parametric oscillator with injection seeding, the oscillator being associated with a pump laser.
