AC voltages applied to the scanner crystal X-Y axes produce a raster-type scan motion as
represented in Figure 2.1g. The horizontal axis presented on the display monitor is referred to as the
“fast axis” (in this example, the X-axis, although either axis may be designated as the “fast axis.”)
and scans at a Scan rate entered by the user. The orthogonal axis is known as the “slow axis” (in
this example, the Y-axis).
