Abstract

For the great importance of measuring turbine rotor bend for both inspection and repair of turbines

an automatic measurement system

which uses a rotating mirror for scanning

double slots for scanning speed calibration

an optoelectric detector for optoelectric change-over

and a microprocessor for processing

display and printing of data

is proposed for measuring turbine rotor bend using laser scanning technology. Experimental results show that the automatic measuring system is capable of doing remote non-contact measurements of turbine rotor bends with an accuracy of ±5 μm from 4 m away.
