Preview of track to be used for discrete scanning.
Collecting data in this discrete manner can be time-consuming. Alternatively, the user can
perform a “Quik-Scan” (discussed below) whereby the stage is moved continuously while
data is collected at uncontrolled points along the track; this is useful for a quick sample
survey to identify regions of interest for more precise study by discrete scanning. The
continuous track can be displayed by pressing the button on the right from
SloScan
to
QuikScan
. Because of the nature of the hardware, the full set of coordinates over which to
continuously move the stage must be uploaded to the stage motion controller.
Acceleration, deceleration, and interpolated points must be constructed from the defined
track, with care taken to avoid the memory and speed limitations of the hardware. This
construction and limitation-checking is automated. If the QuikScan parameters are
improperly set, an error message will be clearly displayed and the graph grayed out. The
user will be offered suggestions as to how to change the parameters to create a valid
QuikScan track.
