The Advanced Video Extensometer A video extensometer is a device that is capable of performing stress/strain measurements of certain materials, by capturing continuous images of the specimen during test, using a frame grabber or a digital video camera attached to a PC. (AVE) from Instron Corp., Norwood, Mass., uses a high-resolution digital camera and real-time image processing image processing Set of computational techniques for analyzing, enhancing, compressing, and reconstructing images. Its main components are importing, in which an image is captured through scanning or digital photography; analysis and manipulation of the image, accomplished to make precise strain measurements on material test samples. Because it is non-contacting, it has no influence on the specimen and eliminates the possibility of damage due to energy release at failure. Having no moving parts, it suffers no mechanical wear that could lead to unreliable results. AVE is available with three fields of view and transverses-train measurement.
