Liquid mirror telescopes - Present and future

Abstract: The work done with liquid mirrors at Laval University is briefly reviewed. The concept appears sound. It is argued that almost any type of astronomical observations could be carried out with liquid mirror telescopes. As an example, it is suggested how spectroscopy could be implemented on small and large LMTs. Some technical considerations relevant to liquid mirror telescopes are briefly discussed. It is argued that, because the advent of very cheap zenith LMTs should decrease the cost per photon by two orders … Show more

“…They also discussed some scaling-up considerations (curvature of the Earth, Coriolis forces), concluding that 30-meter-diameter mirrors should be feasible. Borra (1987) reviews the present status of the concept and speculates on its future.…”
