| Abstract: | The method of measuring deformation direction of object by auxiliary-plate micro-angle-displacement modulation method is proposed. The principle of this method is described emphasislity. In optical system designed, two holographic plates are set up. One is used to record the modulated double-exposure interferogram of measured object. Nonmodulated holographic interferogram is taken in the other plate. The former is used to analyse derforming direction of the measured object. The latter is used to compute quantity of deformation. Calculated formulas are derived. Experimental result is given. |
| Keywords: | Auxiliary-plate micro-angle-displacement modulation holographic method Measurement Mechanical deformation direction |
