摘要：

We report the successful development and operation of a 2.7 m astronomical liquid-mirror telescope. Built at a fraction of the cost of a conventional telescope, it images a half-degree diameter field centered at the zenith. The telescope is equipped with a low-noise 2048 x 2048-pixel CCD detector, operating in TDI mode, which produces continuous imaging of a 20' wide strip of sky with 2 minute integration time. Images with FWHM of 2'' or less are regularly obtained from its present site near Vancouver, British Columbia. This image quality is limited only by atmospheric seeing and star-trail curvature. The telescope is equipped with a series of narrow-band filters, designed to produce 40 point spectral energy distributions from 0.4 to 1.0 mu m of all detected objects. These will allow classification and redshift estimation of approximately 10(4) galaxies and 10(3) quasars to a limiting magnitude of R similar or equal to 21.
