Proposal and Investigation of a New Method for Calibration of Strain Cylinders Using Laser Interferometry

• Abstract:

  This research is to investigate the possibility of calibrating a strain cylinders using laser interferometry, thus to provide a new type of transducer that can provide both force and deformation indications. This new method for calibration of strain cylinders is based on application of a double channel laser interferometer in a force standard machine. Experimental results show that the deformation of a strain cylinder has a definite and stable relationship with the force applied, and can be calibrated and directly traced to the wavelength of laser.
