tom_center_slit
centers the slit of the energy filter
Syntax
cycles=tom_center_slit(delta_Energy_Shift,dark_bright_ratio,max_iterations,State,COMS,platform)
Input:
| delta_Energy_shift | :increment of the slitmovement |
| dark_bright_ratio | :threshold for the edge of zero-loss peak |
| max_iterations | :max number of iterations done to search the edge of zero loss (in one direction) |
| State | :state (structure), to set microscope in certain mode |
| COMS | :structrure including the interface to the microcoscope (ActiveX Server) |
| platform | :use the matlab code below or call digital micrograph routine |
| Output | |
| cycles | :number of iterations needed to center the slit |
Description
The edge of the slit is searched by moving the
energy slit and calculating an Examples cycles=tom_center_slit(delta_Energy_Shift,dark_bright_ratio,max_iterations,handles.Slit,handles.COMS,'Matlab');
intensity ratio between old and new position. If the edge is not found
in one direction the sign of the shift is altered and the search is reversed.
