Abstract :	[en] In the framework of the International Liquid Mirror Telescope (ILMT) project, a new method for testing the optical quality of liquid mirrors has been developed. The optical quality of liquid mirrors may be affected by the presence of wavelets in the liquid layer. This talk explains how it is possible to detect these defects by measuring the deflection they induce to a laser beam reflected on the liquid surface. Moreover, this method allows to characterize the different parameters of the wavelets, making possible to simulate their impact on the point spread function of the ILMT. Focus will be done on the experimental setup of the method.
