Polarizing optical sets for the investigation of strain and force fields in constructive materials
There is a series of polarizing optical sets for the investigation of a stress-strain condition using polarizing optical method. They are intended for research of the difficult rheologic systems in both static and dynamic states. For the dynamic case, the sets are combined with high-speed digital cameras and laser interferometers. The sets KSP-7 and KSP-10 have precise mechanical actuators which allow scanning of the interferometric fields in a wide spatial interval.
Currently, the polarizing optical method is one of the most effective ways to solve difficult problems wherein it is necessary not only to define strain and force fields, but also to determine ‘a priori’ unknown deformation and fracture consistent patterns of condensed matter.
