| Abstract: | A method for calibrating the displacement transducer of a nanoindentation instrument using laser interferometer is presented,and a calibration device is set up.The balanced optical system design makes this device have high stability,which is verified by a zero-displacement test.The displacement of the indenter of a nanoindentation instrument is calibrated using this device,and the results are given.Preliminary experiments and uncertainty analysis show that this interferometeric device should be able to measure the displacement of indenter of a nanoindentation instrument with characteristic uncertainty at nanometer level. |
