【摘要】 A visible laser-based vibration compensation interferometer has recently been designed for the EAST tokamak and the bench test has been finished.The system was optimized for its installation on EAST.The value of the final optical power before the detectors without plasma has been calculated from the component bench test result,which is quite close to the measured value.A nanometer level displacement(of the order of the laser’s wavelength) has been clearly measured by a modulation of piezoelectric ceramic unit,proving the system’s capability.更多还原
