BSD modes
The BSD modes can be selected in the Smart-
SEM
®
user interface.
The
BSD Control
panel summarises the
functions:
•
BSD: COMPO
selects composition imaging (the four seg-
ments arranged in a circle are used in normal
mode).
•
BSD:TOPO
selects surface topography (the four segments
arranged in a circle are used, two in normal
mode and two in inverted mode)
•
BSD:Set TOPO
saves the current segment configuration as a
new TOPO mode
At the top, the diode polarity is displayed.
The diodes can have the following status:
•
Normal (+): The signal is added to the
total signal.
•
Inverted (-): The signal is inverted before
being added to the total signal.
•
Off ( ): No signal is being added to the
total signal.
