5.5.5 Particle Imaging Velocimetry Fixed Exposure Mode
In Particle Imaging Velocimetry (PIV) Fixed Exposure Mode, when an external trigger is applied, the first time
exposure starts the same as PWC mode does. It lasts a very short period (8
μ s). The second time exposure starts
during the transferring time of the first image accumulated in the first exposure time. The second time
exposure continues until the first image transfers completely. The second image is transferred after the second
exposure. There is a short period (500ns) between the first exposure and the second exposure. In order to keep
two exposure periods constant, the LDV is reset before the first image is transferred out.
The maximum trigger frequency in this mode is equal to 1/ (transfer time of two 4 μ s). The minimum
active period of the external trigger is 5 μ s
