[en] We present the achievement of the European PHIFE project (pulsed holographic interferometer for the analysis of fast events) and which consisted in the development of holographic head principles connected to a YAG Q-switch double pulsed laser. An industrial prototype has been built with the aim of Hill-field out-of-plane displacement measurement at a high repetition rate. In parallel, a new double pulse laser with 25 Hz repetition rate, high energy (800 mJ/pulse in single pulse operation), variable delay between pulses (from 1 to 200 mu s) and based on a single cavity is studied
