Liquid Mirror Telescopes: History
A history of Liquid Mirror Telescope (LMT) experimentation is provided. The concept can be traced to Ernesto Capocci of the Naples Observatory (1850), but it was not until 1872 that Henry Skey of the Dunedin Observatory in New Zealand constructed the rst working laboratory LMT. The 1909 experiments by Robert Wood at Johns Hopkins University exposed some of the strengths and weaknesses of the LM...
متن کاملMirror Design For Optical Telescopes
The reflectormirror is the most important component of an astronomical optical telescope. This chapter provides discussions on the requirements for astronomical optical mirrors; the ways to reduce mirror weight, mirror cost, and mirror materials; the methods of mirror figuring, polishing, and surface coating; the design of mirror support mechanism; the concept of mirror seeing; and the stray li...

15 صفحه اولSpectroscopic methods for liquid mirror telescopes
Different methods of spectroscopy with LMTs are described: the objective prism method (a), the parallel (b) and perpendicular (c) long slit methods, the holographic FTS method (d), and the scanning multislit method (e). Advantages and drawbacks of each method are pointed out and estimates of nightly performances are given. Equivalence in the photon-limited regime between all methods offering a ...
متن کاملAstronomical Research with liquid mirror telescopes
I discuss the modalities of zenith observing with LMTs, their limitations and advantages. The main limitation comes from the relatively small regions of the sky that LMTs can access. The main advantage comes from low cost, for inexpensive large LMTs can be dedicated to very specialized goals. Large surveys, cosmological studies, variability studies are prime examples of astronomical research wh...
