Object Mounting Location for Rotary Scanning
In rotary scanning, the laser light is beamed toward the center of the table. This means that when the object is uneven, the penetration of the
laser light varies greatly according to the object's mounting location. This case takes this point into account and deliberately shifts the
mounted position away from the center. Note that plane scanning may be better suited to an object like this one. At this mounted position,
the back portion is not scanned correctly.

Depression is a dead angle
for laser light, and so is not
scanned.
