Functional Principle, Technical Data
3.1
Short Description
3.1.1
Measuring Principle
The scanCONTROL 25xx sensor operates accord-
ing to the principle of optical triangulation (light
intersection method):
- A laser line is projected onto the target surface
via a linear optical system.
- The diffusely reflected light from the laser line
is replicated on a sensor array by a high quality
optical system and evaluated in two dimensions.
The laser line triangulation corresponds in principle
to the triangulation of a laser point. In addition,
during the measurement a row of lines are simulta-
neously illuminated by the laser line. Apart from the
distance information (Z-axis), the exact position of
each point on the laser line (X-axis) is also acquired
and output by the system.

System Setup
The scanCONTROL 25xx sensor is a compact sensor with an integrated controller. All necessary integral
parts are combined in one housing.
