The invention relates to a method for measuring characteristic properties of a plasma beam in a thermal spraying process, wherein the spraying materials are fed into the plasma (1) and the luminous radiation emitted by the plasma (1) is reproduced on optical fibers (2). According to the invention, the luminous radiation is reproduced on the one end (2a) of the optical fibers (2) arranged in a one-dimensional or two-dimensional array (6). According to the invention, spectral analysis of the luminous radiation transmitted in the optical fiber(2) is accomplished with a spectrometer (3) arranged at the other end (2b) of an optical fiber (2). In addition, the frequency spectrums are analyzed in a processor (5) to determine the contemporaneous condition of the spraying process.
