LAP measurement systems – non contact displacement measurement
LAP laser sensors measure dimensions without touching the object’s surface. Production processes can be monitored continuously, ensuring quality and reducing rejects.
LAP measurement systems are flexible and easy to integrate, with very capable software. Having no contact with the object to be measured lets the user work with soft, sticky, hot or other sensitive surfaces. There will be
no wear and tear at the sensor. Keeping the sensors’ windows clean
can be done by air purging.
All systems incorporate laser triangulation sensors. Measurements
of displacement, thickness, width and height, etc can be made.
Depending on the type of system purchased, measurement ranges
from 0.2mm to 4000mm are possible and accuracies down to ±0.1
micron can be achieved.
Based on a Digital Signal Processor (DSP) the intelligent sensor
controls the exposure of the CCD and the output power of the laser
source. Because of this, LAP laser sensors measure extremely
precisely and quickly, even if surface characteristics like colour or
reflectivity are changing. Parameters such as measurement speed
or filters are handled directly in the sensor’s DSP.
