SYSTEM AND METHOD FOR DETERMINING STRAIN

摘要

A system (50) for determining strain includes: a stimulating light source (5 4, 56); a device (64) for placing stress on an object (58); a number of local strain gauges (66) attached to the object (58); and an image capturing devic e (62, 64). A controller (52) is coupled to the stimulating light source (54, 56) and has a signal that turns on the stimulating light source (54, 56). Th e controller (52) receives a strain signal from each of the local strain gauge s (66) located on the object (58). The controller (66) has an image signal tha t determines when the image capturing device (62, 64) captures an image.
