| Zusammenfassung | Advanced novel techniques for sophisticated laser Doppler anemometer applications are presented in this paper. By applying laser sources with high output powers like MOPA-lasers, fiber lasers and booster fiber amplifiers to increase the laser power in the measuring volume and by amplifying the scattered light power with optical fiber preamplifiers to increase the sensitivity of the receiving units, the SNR of laser Doppler signals is drastically improved and the overall performance of a LDA is significantly enhanced. |
