摘要：
The LSST will utilize an Active Optics System to optimize the image quality by controlling the surface figures of the mirrors (M1M3 and M2) and maintain the relative position of the three optical systems (M1M3 mirror, M2 mirror and the camera). The mirror surfaces are adjusted by means of figure control actuators that support the mirrors. The relative rigid body positions of M1M3, M2 and the camera are controlled through hexapods that support the M2 mirror cell assembly and the camera. The Active Optics System (AOS) is principally operated off of a Look-Up Table (LUT) with corrections provided by wave front sensors.
