Annotation:  The paper the study of speckle holographic interferometric processing system specklegram for the control of biological objects.is presented. This system for measuring micro-displacements is relevant, since the measurement error was about 0,1 µm is shown. The work of the system: adjustment of orientation of interference fringes, adjustment of the optical scheme is considered. The deformation of the surface of the biological object – dental tissue was also subject to experimental study. The experimental results of the displacement vector to verify the accuracy characteristics of the system processing specklegram are carried out. Experimentally determined projection dx , which is quite well coincides with the value of d0 – indication of the displacement indicator is determined. The magnitude of the variance of the displacement from the average value for d0 = 5 µm is not greater than 0.1 µm, for d0 = 300 µm – 1.5 µm, which agrees well with the theory The results on specklegram, which was carried out registration of the two object condition in the unloaded state and under load R = 32 kgs are obtained.
