series laser scanners are based on laser triangulation principle. Their first characteristic is the flexibility of the optical setup. In particular, the following parameters can be defined: working distance, scanning length, emitter/receiver inclination, laser light power and wavelength, type of laser emission. This flexibility allows the scanner optimization in function of the specific application.
A thin laser line is projected on the material in the area of interest which defines the section to be inspected. By means of the optical system positioned at a certain angle, the image of the lighted section is projected on a bi-dimensional optoelectronic transducer which provides the X/Z coordinates of the section itself, both along the scanning direction and along the distance variation. In case of material movement along Y direction, it is possible to obtain the continuous 3D inspection of the area of interest.
All the optoelectronic components necessary to provide a usable digital output are integrated in a single device calibrated in a certain working range, with a given scanning length and a specified working distance. The best scanner resolution is obtained with the smallest possible working range and scanning length.
Models are available with integrated data processing for advanced sensors applications, with external processing for graphic display and data storage applications, without processing for OEM applications.
