 note = {A new method for measuring dynamic photoelastic constant by time-averaged holography is described. In this method a rod clamped at one end is longitudinally excited at another end in the ultrasonic frequency range. The stress, that is, the displacement and the variations of refractive indices of the rod are obtained separately from the interference patterns of holograms whose objective beams are the one reflected at the surface of the rod and the one transmitted through the rod. The measuring theory is offered and the experiment is carried out where the specimen made of epoxy resin containing plasticizer is excited with a ferrite vibrator and a step horn. The measured photoelastic constant is compared with the one determined statically. The former is larger than the latter. The dynamic absolute stress­- optical coefficients can also measured, but the accuracy of the measurement is low because the sensitivity of the measurement is low and it is difficult to measure the dynamic Poisson's ratio. This method is easier than the conventional ones.},
