Non-destructive stress measurement in glass, compensates laser beam attenuation by use of neutral wedge filter and increases imaging unit sensitivity |
摘要 |
Scattered light is measured, compensating intensity losses of the laser (2) beam. A neutral wedge filter (8) (or step-wedge filter) is inserted in front of the imaging unit (7), which is switched to a higher sensitivity level. An Independent claim is included for the corresponding apparatus.
