Measurement of the ou 重 一 〇f− plane displacemcnt of a can 丗 ever is perfomled by phase −shifting digital holographic 血 terferomety． Phase − shi 食ing method is used for the phase analysis Qf the hologram recorded on a CCD sensoL ［ ［ he complex amplitude of the reconstructed objecl is obtained from the complex amplitude of the CCD planc using the Fresnel di丗 action algorithm ， The difEerence of the phase distribut 三 〇 ns before and after deformation， i ・ e ・ out ・ of 」 plane displacement is calculated ． 1n order to decrease the e 価ect of speckle pattern ， the hologram is divided 血 to 16 parts ． The phase is ob 吐 aincd from the phase with the maximum amphtude among the complex amplitudes obtained fビom an the separated hoiograms ． As the result ， by eliminating the effect of speckle ， a smooth phase difference distribution is obtained ，
