Hi John,
I'm having troulbe getting the pixel width to be the same in x and y.
I've completed the beam scan calibration using the information from the jeol software.
When I specify 256x192 pixels and 1000 mag in Jeol software. I get a distance of 120x90um. Which is 0.46875 per pixel for both x & y.
When I do the same thing in Probe Image I get a distance of 120 x 67.50 um. So its using a different aspect ratio, but also calculate x per pixel is 0.46875 and calculated y per pixel is 0.3515625.
Also if I type on Probe Image 256x256 I get 120x90um - what am I doing wrong. Oh I get it... Therefore when you do the beam scan calibration you have to enter the X(FOV) and Y(FOV) as a square - rather than what is observed on the SEM screen is this right?
I tried to change ImageInterfaceImageIxIy="1" in probewin.ini from 1 to 1.3333 to reflect the aspect ratio of the jeol SEM screen but this did not help - it just gave a distorted image.
So what I need to do is for the beam scan image calibration take the distances from the image acquired through PFE imaging is that right?
Thanks
Ben
