Abstract
The Large-Sky-Area Multi-object Fiber Spectroscopic Telescope (LAMOST) put forward by Shou-guan Wang and Ding-qiang Su is a special reflecting Schmidt telescope with the spherical mirror fixed and the correcting plate acts as both correcting plate and tractor.

The correcting plate is installed on an alt-azimuth mounting and its aspherical figure is
variable to meet the requirement for eliminate the spherical aberration of the spherical primary mirror when it is at variant orientations during the observation course and for different sky area. With LAMOST, both large aperture and large field of view can been obtained. Benefited from the LAMOST design and practice, a LAMOST-type telescope for
full-sky survey is conceived for the Antarctic. Because of the favorable seeing condition and all-winter continuous observation, a telescope with aperture of the 2-m could be equivalent to the 4-m LAMOST. We preliminarily considered a 2-m telescope with a primary focus and a Cassegrain focus.

The f-ratio of 5 and FOV 3-degree for the primary focus, and f-ratio of 15 and 8 minutes FOV with the diffraction limited image for the Cassegrain focus. In this paper, the scientific goals, the optical system of the telescope, particular material and technique which are applicable under the extreme low temperature condition at the Antarctic are described.
