Abstract
In the framework of the 4-m International Liquid Mirror Telescope project, we have developed an innovative technique to assess the optical quality of liquid mirrors, whose optical quality may be affected by the propagation of wavelets over the mercury layer. We present a method based upon the reflection of a laser beam over the surface and present the mathematical modeling as well as preliminary results obtained from laboratory measurements.
