提出了一種新型太陽光譜望遠鏡的建議,這種望遠鏡能夠同時記錄太陽日面觀測區(qū)域的兩維空間的色散(三維光譜),即一系列同步狹窄帶通的光譜圖像。
The optical correlation function is used to determine the correlation time of atmospheric turbulence, within the time the effect of atmospheric turbulence is taken into account by using the optical transfer function,finally,the optical quality of a large telescope system(with aperture of 500mm,focal length of 500m) is calibrated.
