3.9.4 X-ray Analysis Mode

Scanning modes for analysis are available in the Full and Small screen modes. Use the SCAN MODE block in the operation panel.

(1)Normal mode

Normal image observation mode. Click to return from analysis modes.

(2)Line Analysis mode

Displays a line profile of the signal intensity as a horizontal line in the observing image. The Line Analysis button is used for two scanning modes as follows.

(a) Position Set mode for Line Analysis

Upon the first click of the button in other scanning modes or in Line Analysis mode, a horizontal dotted line cursor is shown on the image. This line cursor corresponds to a position of the scanned line in Line Analysis mode. To position the line cursor, locate the mouse icon near to the line. When the mouse cursor is changed to an intersecting arrow mark , drag the line cursor with the mouse, holding down the left button.

(b) Line Analysis mode

When the Line Analysis button is clicked in Position Set mode, the scanning image is frozen and a waveform, which is a profile of the signal intensity of the line, is shown on the image. You can move the line cursor in this mode with the same operation as above, and you can change scanning speeds.

Use Scanning Speed buttons to select line scan speed. TV or Fast scans with fast speed, useful for SE or BSE signal profiling. Slow1 to Slow5 scans with slow speed, used for X-ray intensity profiling.

When the Back Ground in the LINE PROFILE SIGNAL block on the Setup dialog window – Image tab is checked, the line profile is overlaid on the image. When it is not checked, only the line profile is shown on the screen.

The Run/Freeze button changes run and stop alternately. When scanning is stopped, a profile is re-drawn clearly on the image.

To take a photograph with the line profile, stop the scanning by clicking the Run/Freeze
