Intensity

Intensity Tab

The intensity tab displays the total intensity (total = sum over the polarization angles) image of the stack to be analyzed if the Stack slider in the lower right part of the tab is set to 'T', or the image n of the stack if the value of the Stack slider is set to n. The selected dark value has been removed from the total intensity (see Dark value for more information on the computation of the dark value).

Information on the Navigation toolbar can be found here.

• The contrast can be adjusted with the contrast slider on the right hand side of the tab. This value of the contrast will be used in the intensity images in the figures, but does not affect the analysis.

• Click the button to display the angle (in deg) and the length (in number of pixels) of the segment selected on the intensity image. In order to display the distance in μm, enter the length of a pixel in nm in the entry box right below. The angle is defined counter-clockwise in the field of view (see Angle orientation). Click the left mouse button to select the start and end of this segment.

Note

Click the square button at any time to exit the line segment drawing mode. When the square button is active, it is not possible to use the navigation toolbar (for, e.g., pan, zoom). First draw the line segment, or click again the square button, before using the navigation toolbar again.

The lower left part of the tab indicates the name of the stack to be analyzed.
