Analysis of the Slit-Scanning Control System of the 1 Meter Solar Telescope of YNAO

The 1 Meter Solar Telescope of YNAO is an altazimuth-mounting telescope.Its field of view is of 3'×3'.The slit scanning is required to obtain two-dimensional spectral imaging.This paper describes the overall structure of the slit-scanning control system.According to the optical system of the telescope, we give the mathematical analysis, show the feasibility of the slit-scanning control system, and reveal the effects of some parameter values on the system.
