Digital Image Correlation (DIC) is a popular, non-contacting means of measuring full-field strains from the surface of a deformed object using a high resolution digital camera. At extreme temperatures, DIC is impeded by light emitted by the object which can saturate the camera sensor. A method is presented for mitigating that emitted light by conducting DIC using ultraviolet (UV) lights, cameras, lenses, and filters. It is shown that at lower temperatures for which sample glowing is not an issue, the UV-DIC method obtains the same results as conventional white light and blue light DIC. At higher temperatures, the unfiltered white light showed significant glowing between 500 and 600°C; filtered blue light showed significant glowing between 700 and 900°C; and UV-DIC remains minimally affected up to at least 1125°C. The three methods (which are material-independent) are then demonstrated to measure strains under various thermo-mechanical conditions on a nickel superalloy, Hastelloy X.
