Application examples
1. Emission of laser pulses in millisecond intervals
2. Determination of the time difference between output and input pulse
3. Calculating the distance from the time difference
Application examples
2. The Phase-shift method
MeASURING PROCEDURE
1. Emission of modulated laser light
2. Comparison of the reflection signal with the reference measurement
3. Distance calculation based on the phase shift between output and input wave
•
Material presence, width and parallelism
determination
•
Permanent position detection and positioning
•
Material flow tracking; event reporting
•
Frame cutting and cutting of semi-finished products
•
Edge detection in the casting process
•
Coil position and residual length measurement
•
Level measurement of gas containers
•
Loop control in the silo
3. The Pulse backmixing method
SPECIAL FEATURES
1. Very high time resolution of 10 -12 (ToF laser 10 - 9)
2. Calibration pulse with time stamp before each measurement
3. Very high measurement rate with modulated light as pulse (no continuous light)
Application examples
•
All high-temperature processes that require high measuring rates
This method is a combination of phase-shift and time-of-
flight measuring.
4. The Laser-Doppler-Interferometry
MeASURING PROCEDURE
1. Generation of a laser Doppler stripe by two laser beams on the
product surface
2. Collection of the reflected Doppler signal by the receiving optics
3. Signal processing into accurate, reliable and repeatable data
Application examples
•
All continuous production processes
•
Plastic sheet production
•
Paper and film production
•
Steel production
•
Tube and cable production
•
Textile production
1. The electro-optical Time-of-Flight method
MeASURING PROCEDURE
