An improved approach to eliminate the error induced by vibrations for laser speckle interferometry under tokamak vibrational environments

An improved approach to eliminate the error induced by vibrations for laser speckle interferometry under tokamak vibrational environments

To build an online and non-contact diagnosis system of surface morphology of Plasma-Facing Components (PFCs) in fusion devices, a measurement system based on Laser Speckle Interferometry (LSI) is in development in our laboratory. To preserve high resolution, the temporal phase-shifting technique whi...
