Technical description

4.1

The laser system in use
POLARIS laser sensors are used to measure the distance
or the thickness of standing or moving objects. By using
this measurement system, you can monitor your production completely and document the quality of the product for
the customer with production logs.
The laser sensors are suitable for industrial applications.
They can be used in any production situation to test individual parts in the laboratory and for online production
control. Impacts to the devices and scratches on the protective glass panels could impair the functionality of the
devices and must be avoided.
The laser sensors operate with a max. sampling rate of 4
kHz. Both digital and analog measurements are output.
For diagnostic purposes, a video signal can be evaluated
using the diagnostic and parametrisation tool.
Several lasers can be operated at one RS485 interface.
The laser sensor parameters can also be checked and
modified via this RS485 interface. For this operating
mode, however, each sensor must first be assigned a dedicated address. The diagnostic and parametrisation tool is
used for this purpose.
Some of the accessories offered by LAP:

4.1.1

•

Laser sensor holder (see chapter 7.1) for installing
and removing the POLARIS laser sensors easily

•

RS485 / USB converter for connecting the POLARIS
laser sensors to a USB interface

•

Interface modules (see chapter 14.2) for processing
binary and analog signals as well as for connecting
encoders to the RS485 network.

•

User software for processing measurements and visualizing several laser sensors.

•

Complete, customer-specific solutions.

Operating principle
The measuring principle of the POLARIS laser sensors is
based on the laser triangulation principle. A laser beam
generates a point of light on the measured object which is
imaged by a lens on a CCD line mounted to one side of
the laser.

© LAP GmbH, MAN-1104 Rev.2.6-en-GB, 2015-01

19

POLARIS Laser sensor 10 ... 400

Depending on the distance between laser and measured
object, the position of the exposed pixels on the CCD line
changes.
The exposed pixels are evaluated and the dimension of
the relevant object status is determined by processing signals via a digital signal processor (DSP).
The calculated distances are output or queried via the
RS485 bus and the analog output.
In addition, the limit values of the measured values can be
monitored. To this end, two limit value outputs are implemented whose respective limit values can be set in the diagnostic and parametrisation tool under "Filters / Limit
Values".
All objects which are neither very reflective nor transparent
can be measured.

Measuring principle (diagram)

The computer used for the diagnostic and parametrisation
tool software must have an RS485 interface, e.g. the USBto-RS485 adapter from LAP. For further information
please refer to chapter 14.1 of this operation manual.
Information on the wiring of the laser sensors and the
functions of the display LEDs is presented in chapter
4.2.4.
The POLARIS laser sensors can also be operated via the
digital intermediate transfer module POLARIS CONNECT
or POLARIS HUB module. For notes and information on
this, refer to the corresponding description of functions
and operation.

Thickness measurement using two laser sensors

Thickness measurements are possible using two
POLARIS laser sensors. In this case the user must ensure
that the surface of the measured object never leaves the
measuring range of the corresponding laser sensor on either side of the measured object (see Fig. 4-1: Representation of the measuring ranges).
Each laser sensor must therefore be mounted so that the
end of its measuring range covers the surface of the
measured object at the farthest possible distance.
The measured value 0 corresponds to the point farthest
away. The measured values increase towards the POLARIS.
In the marginal case of an absolutely flat, extremely thin
measured object, the clear width is the sum of the distances of both ends of the measuring range.
The middle of the measuring range and the clear width are
shown in the following diagram for the sake of clarification.

Converting the sensor value to a measured value
The value range of the sensors is 2768 to 62768 and is
independent of the sensor's measuring range. The value
2768 corresponds to the end of the measuring range that
is farthest away from the sensor and the value 62768 corresponds to the end that is closest to the sensor.
The actual measured value in mm is obtained by subtracting 2768 from the sensor value and then multiplying the
difference by the sensor's measuring range and dividing
by the resolution (60000). The following equation can be
used:

Fig. 4-2:

Measured value formula

This yields the settings for the Wetec display converter:
•

Scale factor = measuring range / 60000

•

Offset = 2768 x measuring range / 60000

This results in the following for the inverse representation
of the measured value:

General POLARIS data

Comments regarding measuring frequency: With the default factory settings, the POLARIS DSP controls both the
laser power and, if that is insufficient, the exposure time of
the CCD line in real time to obtain the optimum measurement results. If the application requires, a fixed exposure
time of 250 µs is possible.
