Scanners

Our two high precision O2DS scanners series is optical laser devices for non-contact  measurement in two dimensions. The two series, X and XL, have different physical dimensions, and each series covers several different measuring ranges and different resolutions.
 

The two O2DS series is laser scanners of the Flying Spot type developed for the need of 2D- / profile-measurement in any kind of industrial application. The ruggedly constructed scanners are designed to give a very reliable measuring performance with high measuring accuracy. Small scan angels and/or high measuring frequencies create very high angular resolutions. Another advantage of the Flying Spot principle is the use of a single spot instead of a laser line. The intensity of the laser light is furthermore continuously adapted by feed back to the optimal intensity for the surface of the application.

The measurement is performed by oscillating the triangulation plane over an angel. The angel can be specified to a maximum of 50°. A fine collimated or focused laser beam is diffusely reflected from the surface of almost any kind of object, and a CCD-camera records the image through an objective. This makes it possible for a Digital Signal Processor to precisely determine the radial distance from the centre of the mirror axis to the surface of the target, as well as keeping track of the angular reference position.

Each series covers 4 different measuring ranges. The smallest is 100 mm, measuring from 80 to 180 mm and the largest is 1.400mm, measuring from 700 to 2.100 mm. The resolution varies from 0.1 mm to 0.8 mm. The smaller the measuring range is, the better the resolution will be. O2DS models are available with measuring frequencies of 2 kHz or 6 kHz.

The O2DS measuring system is a compact unit where optics, CCD-camera, and digital electronics all are integrated. There is no need for a separate controller unit. The output is a serial interface RS422. For the 2 kHz O2DS also RS232 is available. The actual interface to the application software is a DLL library for programs running under Windows.

For high temperature non contact measuring the HT (High Temperature) versions are the answer. As a rather unique feature the VVHT version are capable of measuring on extreme hot target surfaces up to 2.000ºC using.

A few examples where the O2DS scanners are being used:

Food Industry:
Measuring volume of cheese before it is cut out in segment and equal weight.

Metal Industry:
Measuring side profiles of aluminum slabs.

Steel Industry:
Measuring height of large steel slabs instead of thickness from above and below.

Car Industry:
Profile measuring tyre sides.
