We present a design for a compact residual stress measurement sensor based on laser annealing and laser speckle interferometry. The instrument integrates laser diodes, holographic optical elements, a compact CO2 laser, and advanced data reduction techniques to provide quantitative measurements. In this paper we present a review of residual stress measurement using laser annealing, details of our design and preliminary measurement data.
