liquid mirror telescope; ILMT; surface quality test
Abstract :
[en] The ILMT is a four meter diameter liquid mirror telescope built in Liège by a collaboration of astronomers from Canada, India, ROB and ULg. In January 2011, for the first time, the mirror was tested with liquid Mercury. After reminding liquid mirror basics, we present the different phenomenons that may affect the mirror surface quality. We then present a method created to test the ILMT surface quality and we summarize the course of the recent mercury tests.
