Overlap ON (meaning exposure to light while simultaneously reading out charge from previous exposure).To use the Zyla or Neo sCMOS cameras for PIV we recommend the following camera settings:. These particles are illuminated, normally by a laser pulse or strobe, to enable their location to be imaged. These particles enable the flow of the medium to be observed without altering the movement. The technique usually requires some particles to be seeded into the medium in order to be observed. The key timing parameter is the time Δt between the illumination pulses as this determines the temporal resolution for the two images, which are then processed to produce a suitable vector map derived from this time differential. The synchronization unit provides two pulses to the laser, or illuminating source, causing it to fire, once near the end of the exposure of the first image and then again at the beginning of the second exposure. The length of the camera exposure is normally not a key requirement, with relatively long exposures commonly being used. The camera is configured to acquire a pair of exposures (although multiple exposure pairs can be configured) of the sample plane with minimal delay between the exposures. The laser and camera are integrated using a device, such as the synchronization unit shown above, which will act as the master timing control unit. The laser’s beam is fantailed by a cylindrical lens to illuminate a plane of the sample which is imaged by the camera.

Temporal resolution is a key parameter in this technique. A PIV set-up typically includes the following equipment:.

It is also possible to use 3rd party acquisition software environments such as LabView or MatLab. The acquisition type described can be configured either in Andor Solis acquisition software or through use of the Andor Software Development Kit (SDK3).
#ANDOR SOLIS SPOOL EXTERNAL TRIGGER HOW TO#
This tech note details how to integrate the Andor Scientific CMOS (sCMOS) family of cameras, Neo and Zyla, into a PIV setup. Particle Imaging Velocimetry (PIV) is an optical method of flow visualization used in research and industry to obtain velocity measurements and related properties in fluids.
