      像质检测方法特点与MTF检测法对比
      星点法空间域目标信息描述,可进行衍射限系统所成星点像光强分布与实际系统星点像光强分布比较;难以定量测量,对轴上球差不灵敏[15];直观,简便。 频率域目标信息描述,可定量测量,通过比较实测值与理论值差异可鉴别不同像差影响[11]
      目视分辨率法反映截止频率附近的像质情况,直观,简便,可定量;难以获得低频信息,受测试者主观因素影响大[15]低频信息到高频信息的连续反映,不受主观因素影响;测量相对复杂。
      波像差法单色光测量,表征图像清晰度不直观,测量精度高,可反映装调的微小误差及镜面变形,反映不同像差,求解装调问题[16]复色光测量,客观、灵敏、定量的像质评价手段。
