The laser line triangulation corresponds in principle to the triangulation of a laser point.
In addition, during the measurement a row of lines are simultaneously 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.
3.1.2 System Set-up
The scanCONTROL28x0 measurement system consists of a compact sensor and an
intelligent controller which are connected together via an extendable connecting cable.
The controller can output the measurements of the two axes or, optionally, coupled
values. The user can also select from several evaluation functions (modes).
3.1.3 Special Performance Features
• scanCONTROL features speed with simultaneously high measurement accuracy. A
special line-scanning optical system ensures uniform illumination of the measuring
field.
• The CMOS array is arranged in the sensor head according to the Scheimpflug
condition which facilitates uniform image focusing over the whole depth
measurement range (z axis).
• In conjunction with saved configurations scanCONTROL 28x0 measurement
system is also capable of functioning without a PC. The measurements are either
output via two analog outputs (x-z profile or parameters) or can interact with a PLC
via the digital inputs/outputs.
Advantages of the used CMOS array (difference to normal video matrices):
• The high resolution CMOS array has 1024 x 1024 pixels and freely selectable access
to preselected areas. Consequently, the geometry of the measuring field (height Z
and width X) can be varied and can be adapted to the measurement application.
• With fast moving objects a high profile accuracy is achieved for the complete
profile using a global shutter (high speed shutter).
• The array enables the simultaneous exposure and reading out of theprevious image.
As a result, exposure can be for longer with the same profile frequency and hence
also dark objects can be measured at high speed.
Further features
• External synchronization and triggering.
• Two serial interfaces (RS232 and RS422) for communication with PLCs or PCs.
• FireWire connection (IEEE 1394) as fast standard link to the PC.
• Video output for adjustment purposes.
• The automatic control of the illumination time enables consistent measurement
results with changing surfaces. This function can be switched off on request.
