Image Optimization 5-49
z Linear scanning
Move the probe across the surface. See the following figure.
z Rocked scanning
Rotate the probe once from the left to the right side (or from the right to the left)
to involve the whole region desired. See the figure.

Parameter Description
Method
Function: select the image acquisition method.
Selection: Rocked, Linear.
Linear mode: during the sweep, the probe may not be moved parallel, the
speed at which you scan should be constant, about 2cm/s.
Rocked mode: in this mode, the probe must be moved to a position where
you can clearly see a middle cut of the object you want to scan and render.
Tilt the probe to about 30 degrees until the object you want to scan
disappears. Start the acquisition and tilt the probe over a distance of around
60 degrees until the object disappears again. During the sweep, the probe
may not be moved parallel, just tilted. The speed is about 10°/s-15°/s.
Tips: the speed is related to scanning distance or angle.
Distance
Function: to set the distance the probe covered from one end to the other
end during a linear sweep.
Range: 10-200mm, in increments of 10mm.
Angle
Function: to set the angle the probe covered during a rock sweep.
Range: 10-80°, in increments of 2°.
