FlowMaster 时间分辨PIV 开创了一片流体动力学分析的新天地。采用这种技术可以把数字PIV测量
所获得的空间分布信息和每个点随时间的演化发展过程结合起来。
时间分辨PIV 能够测量流体的速度和加速度场，以及瞬态变化对象的湍流度等相关参量。时间分辨
PIV测量所得到的信息开辟了流体随时间的变分和相关研究的新领域。这种技术能够获得关于瞬态
和湍动的“真实”参量。
LaVision的 FlowMaster 时间分辨PIV系统 include state-of-the-art digital high-speed cameras with several kHz frame rate at full resolution of up to 2k x 2k pixel and several
100 kHz frame rate at reduced resolution. Single or dual cavity high-repetition rate solid state
lasers up to several 10 mJ per pulse and up to 20 kHz repetition rate
are available. All components are fully controlled from the DaVis software and LaVision`s
unique High Speed controller (HSC). The HSC enables an easy use of high speed systems
even on engine or rotating machine applications with typically demanding trigger requirements
like the synchronization of the external frequency of the device with the recording rate of the
measurement system.
