Operating principle of the NAV350
The NAV350 has an opto-electronic laser measurement system that electro-sensitively
scans the contour of its surroundings in a plane with the aid of laser beams. The NAV350
measures its surroundings in two-dimensional polar coordinates. If a measurement beam
is incident on an object, the position is determined in the form of distance, direction and
remission.

Measuring principle of the NAV350
From the propagation time that the light requires from emission to reception of the reflec--
tion at the sensor the NAV350 calculates the distance to the object.
Scanning takes place in a sector of 360°. The scanner head rotates at a frequency of 8 Hz.
During this process, a laser pulse and therefore a distance measurement is triggered after
an angular step of 0.25°.
