Abstract: A method for reducing fringe interference of light created in a passive cavity defined by partially reflecting optical surfaces in a laser spectroscopy system, wherein the optical path length of the cavity is varied with a triangular back-and-forth movement (x). In accordance with the invention, the spectroscopic measurement is performed in successive measurement cycles with a time interval between each two successive measurement cycles, the triangular movement is performed such that the turning points of the triangular movement (x) are positioned in successive ones of the time intervals, and after each or at each n-th measurement cycle, the time position of the turning points is moved relative to the measurement cycle.

Abstract: An apparatus for reducing fringe interference of light created in the optical system of a laser spectroscopy system comprising an electromagnetic actuator for generating, along a laser path, physical translational vibration of an optical element of the optical system and a control device for controlling the amplitude and frequency of said vibration. The optical element is arranged on a cantilever body which is, at one end, attached to a base by a flexural pivot and, at the other free end, coupled to the electromagnetic actuator, and the control device includes a controller that controls the amplitude of the vibration and a vibration sensor attached to the cantilever body and providing the actual vibration value to the controller to improve fringe interference reduction, especially with longer wavelengths.

Abstract: A method and system for measuring the concentration of a gas component in a measuring gas a provided. The wavelength of a light source is modulated with a modulation signal at a modulation frequency, while the wavelength is swept over an interaction feature of a sample. The intensity of the light source is further modulated at a wavelength outside the interaction feature with a burst signal, where an N-th harmonic of the burst frequency coincides with an M-th harmonic of the modulation frequency. The light is passed to the sample and thereafter to a detector. The detector output is demodulated at the M-th harmonic, and the demodulated detector output is normalized by calculating the ratio between a demodulated detector output portion derived from the light modulated with the modulation signal and another demodulated detector output portion derived from the light modulated with the burst signal.
