[0002] One of the core functions of an optoelectronic pod is to acquire clear and accurate optical images. In a rotating state, the internal optical system (such as lenses, detectors, etc.) of the pod can be evaluated for image quality changes in a dynamic environment. For example, at high speed rotation, due to factors such as inertia and vibration, the optical elements may experience slight displacement or deformation, resulting in image blurring, distortion, and other problems. Through rotary table testing, these image quality changes can be quantified to determine the image quality stability indicators of the pod at different rotation speeds and angles, such as resolution, contrast, modulation transfer function (MTF), etc. The current rotary test state lacks a mounting base compatible with the optoelectronic pod, and a custom mounting base is required. The test rotary table cannot be adapted to the fastening installation of most optoelectronic pods, and needs to be improved.
