【 摘 要 】

In this study optical arrangement was applied to find pressure of air and water with macro impurities using laser speckle, the uses this technique need available and cheap devices. Experimental method was done in the laboratory environment and got results of sense pressure change using laser diffraction (LD). Remote sensing for small change in pressure of impurity fluid was detected by utilize CCD camera connected with personal computer, in this technique the relation of change in pressure with changes in the images which represented by Fraunhofer diffraction ring from circular aperture that appears after image processing by MAT LAB program.
