目前的自适应光学系统大多数都没有对光路中的振动进行适当的补偿,因此,在天文自适应光学系统中,减小振动的影响是非常重要的。科学光传输过程中的机械振动效应严重影响了LBTO/AO系统的性能。对望远镜结构上的金字塔波前传感器数据(PWFS)和加速度计网络数据(OVMS+)进行了基于频率的分析,以识别主要的机械振动频率。
The majority of current Adaptive Optics (AO) systems do not compensate properly for vibrations within the optical path. For this reason the mitigation of vibration effects in astronomical AO systems is extremely important. The mechanical vibration effects, acting in the science light propagation path, strongly affect the performance of the LBTO/AO system. A frequency-based analysis of the pyramidal wavefront sensor data (PWFS) and the accelerometers network data (OVMS+) on the telescope structure was done in order to identify the principal mechanical vibration frequencies.
