Signal Processing Evaluated by Allan and Hadamard Variances

Popis výsledku v původním jazyce

Laser spectrometry offers high sensitivity and broad dynamic range, permitting monitoring of concentrations from trace values to the saturation level. Such techniques are increasingly used for field laser applications in industry and research. Photoacoustic spectrometry has been used as an in situ method for observation of actual concentrations combined with high spatial and time resolution. Photoacoustic spectrometry is based on the photoacoustic effect and in conjunction with lasers has already been used in monitoring of industrial trace gas components at ppb concentrations. It has been proven that the characteristic of laser frequency/wavelength stability is critically important for evaluation of metrology system performance when the function principle is based on photoacoustic spectrometry. In particular, the long-term stability range, corresponding to noise in the hundreds of hertz to kilohertz bandwidth, strongly affects the measurement final accuracy at the reported measurement
