Comments |
The GIF introduces a rotation of about 135 degrees between what is seen on the fluorescent screen and what is captured on the CCD. Use this to rotate a captured image by the appropriate angle (edit the magicangle variable in the script to match your system). This makes it much easier to relate particles seen on the fluorescent screen with those in the GIF image (via the rotated image). This is handly where you want to set up fine probes on the TEM screen for EDS or EELS, and then label the corresponding particles the image. |

// Script to rotate the foremost image captured on the GIF CCD to // align its rotation with that on the TEM fluorescent screen. Use this tool to aid finding features // in the CCD image originally sighted on the TEM screen.
// version:20040122,v1.0
// The magic angle variable, is the variable which determines the rotation between // the TEM and the CCD. This angles was determined for a JEOL 2010F and a GIF2000 // system at a magnification of 1000x (GIF button depressed). The rotation does // change slightly with magnification so the match may not be perfect. Rotation is expressed // as number of degrees of clockwise rotation required to bring the CCD image in alignment // the image on the TEM screen. The bit of maths at the end is because the rotation function uses // radians of anticlockwise rotation as its input.
