ABSTRACT:
A process and a device for measuring, through a holographic technique, the deviation of the light rays of a laser beam by more or less transparent objects. The angular deviations (a) of light rays that have passed through the object are measured by an angular measuring instrument (2) located behind an optical system traversed by the light emanating from the object or a hologram formed from the object. The optical system comprises for example one or several lenses (l1, l2), the holographic images forming in the object focal plane of the system, and a diaphragm (D3) located in its image focal plane. The measuring can also be carried out, for example, by turning over the obtained hologram of the transparent object and examining it through a diaphragm. The present invention has application, for example, in the study of flames, of liquid or gaseous flows with strong density variations, of turbulent gaseous mixtures in the combustion chambers of engines, etc.
