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...
