Pulse Width Control Trigger

3.3.6

Particle Imaging Velocimetry Fixed Exposure Mode

In Particle Imaging Velocimetry (PIV) Fixed Exposure Mode, when an external trigger is applied, the first

exposure starts the same as it does in PWC mode. 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

3.3.7

PWC PIV Mode

The PWC PIV mode is based on PIV Fixed Exposure. In this mode, the first time exposure is controlled by the
pulse width of the external trigger, which is similar to PWC mode. The real exposure time of the first image is
equal to the pulse width of the external trigger.

The maximum trigger frequency in this mode is equal to 1/ (transfer time of two exposure time of the
first image).

The minimum active period of the external trigger is 10 pixel clocks (250ns)
