    • An optical apparatus comprising a first mirror (12), a second mirror (14), and at least one support (30) for holding the second mirror in substantially a predetermined position relative to said first mirror (12), wherein said at least one support (30) comprises at least one actuator (32) arranged to adjust the position of the second mirror (14), and said optical apparatus further comprises at least one light source (40a-40-c) rigidly fixed to the first mirror (12) in a predetermined orientation for providing a beam of light (42a-42c) directed at said second mirror (14), at least one corresponding alignment sensor (46a-46c) for detecting the beam of light (44a-44c) reflected from said second mirror (14), and arranged to provide an output signal indicative of the position of the incident reflected beam, and a controller (50) arranged to receive said output signal, and to thereby control said actuator (32) to adjust the position of the second mirror (14).
    • 一种光学装置,包括第一反射镜(12),第二反射镜(14)和至少一个用于将第二反射镜相对于所述第一反射镜(12)保持在基本上预定位置的支撑件(30),其中所述至少一个 支撑件(30)包括布置成调节第二反射镜(14)的位置的至少一个致动器(32),并且所述光学设备还包括刚性地固定到第一反射镜(...)的至少一个光源(40a-40-c) 用于提供指向所述第二反射镜(14)的光束(42a-42c)的至少一个对应对准传感器(46a-46c),用于检测从所述第二反射镜(14)反射的光束(44a-44c) 所述第二反射镜(14),并且被布置成提供指示入射的反射光束的位置的输出信号;以及控制器(50),其布置成接收所述输出信号,从而控制所述致动器(32) 的第二反射镜(14)。
