GEAR MEASURING DEFORMATIONS

摘要

FIELD: measurement technology. SUBSTANCE: invention refers to determination of deformations of parts and samples by optical methods. Gear has laser, system splitting its light flux into two beams which two end elements are connected to deformed object, means to record interference picture and means to process them. End elements of system that splits light flux are connected to deformed object through straps placed with clearance relative to one another. Each strap is anchored in one point of deformed object and end elements of system splitting light flux are made fast to straps. Materials used for manufacture of straps are so selected that end elements do not displace with regard to each other with change of parameters of environment. EFFECT: improved stability and reliability of gear. 2 cl, 2 dwgo
