【摘要】：熱問題貫穿了望遠(yuǎn)鏡設(shè)計(jì)的各個(gè)方面,而且隨著望遠(yuǎn)鏡口徑的增大,溫度對望遠(yuǎn)鏡的工作性能和穩(wěn)定性的影響也越來越明顯。望遠(yuǎn)鏡的主鏡作為望遠(yuǎn)鏡系統(tǒng)中關(guān)鍵的光學(xué)元件,對望遠(yuǎn)鏡的成像質(zhì)量有著重要的影響,為了克服主鏡視寧度對望遠(yuǎn)鏡成像質(zhì)量和望遠(yuǎn)鏡主鏡溫度梯度導(dǎo)致的熱變形對望遠(yuǎn)鏡成像質(zhì)量的影響,對望遠(yuǎn)鏡主鏡溫度進(jìn)行合理地控制顯得十分的必要和重要。本文結(jié)合國外大口徑望遠(yuǎn)鏡,詳細(xì)論述了現(xiàn)代望遠(yuǎn)鏡主鏡熱控的原則,總結(jié)了望遠(yuǎn)鏡熱控設(shè)計(jì)的方法,并進(jìn)行了相應(yīng)的探討,為今后的大口徑望遠(yuǎn)鏡的主鏡熱控設(shè)計(jì)提供一定的參考價(jià)值。
[Abstract]:The thermal problem runs through all aspects of telescope design, and with the increase of telescope caliber, the influence of temperature on the performance and stability of telescope becomes more and more obvious. As the key optical element in the telescope system, the primary mirror of the telescope has an important influence on the imaging quality of the telescope. It is necessary and important to control the primary mirror temperature reasonably in order to overcome the influence of the primary mirror viewing degree on the imaging quality of the telescope and the thermal deformation caused by the temperature gradient of the primary mirror of the telescope. In this paper, the principle of thermal control of modern telescope primary mirror is discussed in detail, the design method of thermal control of telescope is summarized, and the corresponding discussion is made. It provides a certain reference value for the thermal control design of the main mirror of the large aperture telescope in the future.
