The optical manufacturing for off - axis aspheric mirrors has become increasingly challenging for two reasons . the mirrors , in addition to being larger , are more aspheric and off - axis in order to meet the requirement of next generation space camera , which is commonly configured as three - mirror - anastigmat ( tma ) to get both wide fov and high resolution , and the required accuracy is more stringent 近年來,人們提出了“離軸三反消像散” ( tma )結構來滿足下一代空間相機“詳查”和“寬覆蓋”的技術要求,該結構中要求使用三塊離軸非球面反射鏡,而大口徑、高精度離軸非球面反射鏡的制造技術是研制tma結構空間相機的主要技術瓶頸之一。
