1. An extensometer system for measuring deformation on a test specimen comprising:
one or more light sources to direct light to a surface of a test specimen and a screen including a collimating filter, wherein the test specimen is arranged between the one or more light sources and the screen; and
an imaging device to capture images of the test specimen while subjected to a stress-inducing force via a testing system, the imaging device configured to transmit the images to a processor to calculate deformation of the test specimen as a result of the stress-inducing force.
