Dialogue box “Imaging scale/time interval” is opened with menu “Edit \ Scale & time” in the start window. It is used to determine the imaging scale and time interval for PIV recording evaluation. The imaging scale can be input by three ways: (1) inputting field of view, (2) inputting ruler resolution, and (3) inputting calculated image-to-object ratio. The unit of the physical length can be set as mini-meters or inches.
Field of view edit boxes
Ruler image edit boxes
Edit box “Img/obj ratio [pix/m/]”
It is used to directly input the imaging scale with unit of pixel per meter.
Edit box “Time interval [mu-s]”
It is used to input the time interval between PIV exposures with unit of microsecond.
Radio box “mm” and “inch”
They are used to switch metric and English system for the length unit.
Button “2P calibration”
When two calibration markers are selected in “Evaluation” window with menu “Tools \ Calibration markers \ Individual search”, the imaging scale can be determined by pressing this button.
