Abstract:
The article presents the results of theoretical and experimental studies on the application of a ring aperture diaphragm in speckle interferometry. It shows that the application of an annular aperture diaphragm allows to use the objective lenses with a large entrance aperture. This allows to increase the measurement range and sensitivity by the method of speckle interferometry.

Keywords:
ring aperture diaphragm, speckle interferometry.
