SICK nanoScan3 I/O

Scan cycle time and resolution
T
he time that the mirror requires for one rotation is called the scan cycle time. The
number of light pulses per unit of time is constant. The scan cycle time and the number
of light pulses per unit of time determine the angular resolution. The scanning range for
a given object resolution depends on the angular resolution. The object resolution indi‐
cates the minimum size that an object must be to allow it to be detected safely. The
scan cycle time also influences the response time.
The resolution in protective fields can be set to various values according to the
intended purpose.
Geometry of the scan plane
T
he laser beams emitted cover a sector of a circle, so an object can be detected in an
area of up to 275°.
The sector of a circle covered ranges from –47.5° to 227.5°, where 90° denotes the
axis of the safety laser scanner from the back to the front. When viewing the safety
laser scanner from above, the direction of rotation of the mirror and the deflected light
pulses is counterclockwise, see figure 4, page 12.
