Optical sensor for measurement of an object In-plane translation and rotation by speckle correlation method
 Horváth, P. ; Šmíd, Petr ; Hrabovský, M. ; Hamarová, I.
The paper presents design and experimental verification of an optical sensor for non-contact detection and quantitative evaluations of both in-plane translation and rotation of object’s surface by speckle correlation method. This sensor enables to detect both of the small deformation tensor components without change in geometrical parameters of the set-up and hence its conversion.

Bezkontaktní měření rychlosti pohybujícího se tělesa využitím korelace polí koherenční zrnitosti
 Vašková, I. ; Šmíd, Petr ; Horváth, Pavel ; Hrabovský, Miroslav
This contribution contains description of a speckle pattern correlation method for detection of time-variable processes, especially measurement of moving object velocity. The introductory part is devoted to a general principle of the measurement method, then attention is focused on measurement of velocity of an aluminum object under investigation. A designed experimental setup is described and some of the achieved results are mentioned.
