Optical detection equipment (ODE) is subjected to vibrations that hamper the quality of imaging. In this paper, an active vibration isolation and compensation system (VICS) for the ODE is developed and systematically studied to improve the optical imaging quality. An active vibration isolator for cameras is designed, employing a dual-loop control strategy with position compensation and integral force feedback (IFF) control, and establishing the mapping relationship between vibration and image quality. A performance metric for evaluating images is also proposed. Finally, an experimental platform is constructed to verify its effectiveness. Based on the experimental results, it can be concluded that the proposed VICS effectively isolates vibrations, resulting in a reduction of 13.95 dB in the peak at the natural frequency and an 11.76 Hz widening of the isolation bandwidth compared with the system without it. At the same time, the experiments demonstrate that the image performance metric value increases by 46.03% near the natural frequency.
光学检测设备（ODE）会受到振动影响，这会妨碍成像质量。本文开发并系统研究了一种用于ODE的主动隔振与补偿系统（VICS），以提高光学成像质量。设计了一种用于相机的主动隔振器，采用具有位置补偿和积分力反馈（IFF）控制的双环控制策略，并建立振动与图像质量之间的映射关系。还提出了一种评估图像的性能指标。最后，构建了一个实验平台来验证其有效性。基于实验结果，可以得出结论，所提出的VICS有效地隔离了振动，与没有该系统的情况相比，固有频率处的峰值降低了13.95 dB，隔离带宽拓宽了11.76 Hz。同时，实验表明，在固有频率附近，图像性能指标值提高了46.03%。
