Diffractographic Dynamometer

Applied Optics, 1972
A recent paper has described a new diffractographic sensor utilizing a changing single slit diffraction pattern to determine torque in rotating or stationary shafts (T. R. Pryor, O. L. Hageniers, and W. P. T. North, Soc. Exp. Stress Anal., in press). In that experiment, diffraction pattern fringe spacing was visually measured and found linearly related
