对光子多普勒测速(PDV)的基本原理和光学外差技术进行了阐述,对时分、波分、波分时分联合等三种多路复用光子多普勒测速(MPDV)复用方案进行了深入的分析,并指出了各种方案适宜的多点测速类型。根据理论分析结果,设计并搭建了一套2路波分加2路时分的MPDV,并设计了爆轰实验装置,同时利用该装置进行了爆轰加载铝飞片的验证实验。结果表明,较好地实现了MPDV技术,并从其复用了4个测点速度信息的1路干涉信号中,分别解读出了各个测点的多普勒频移曲线及速度曲线,最高速度达到2.5km/s,飞行时间达到16μs,同时验证了MPDV与常规PDV和外差式PDV在静态干涉信号、多普勒频移曲线、速度曲线等方面的差异性和相同点。研究结果对于研究大数量点数MPDV有重要的参考意义。 The basic principles of photon Doppler velocimetry (PDV) and the optical heterodyne technique are described. Three multiplexed photon Doppler velocimetry (MPDV) multiplexing schemes, such as time division, wavelength division and time division multiplexing, are performed In-depth analysis, and pointed out that a variety of programs suitable for multi-point speed type. According to the theoretical analysis results, a set of 2-way wave plus 2-way MPDV was designed and built, and a detonation experimental device was designed. At the same time, the device was used to verify the detonation-loaded aluminum flying-blade. The results show that the MPDV technology is well realized and the Doppler frequency shift curves and speed curves of each measuring point are respectively read out from the 1-way interferometer signals multiplexed with 4 measuring points speed information. The maximum speed It reaches 2.5km / s and the flight time reaches 16μs. At the same time, the differences and similarities between MPDV and conventional PDV and heterodyne PDV in static interference signals, Doppler shift curves and velocity curves are verified. The results of the study for the study of MPDV large number of points have important reference value.
