Abstract: 

This article aims to explain the principle  of a vibration  measurement method based on photogrammetry, and to determine the corresponding uncertainty. The system used is specific : one ultra-fast  camera and a set of mirrors generating two virtual cameras. Numerical simula- tions were carried out in order to quantify the measurement uncertainties and to determine the optimal configuration of the system
