The wavefront of the light wave is measured in real time and the data is fed back to the deformable mirror assembly in real time to adjust the wavefront
The adaptive optics system uses dynamic adjustment technology to compensate the distortion encountered in the optical system during the propagation of light waves. This technology is essential for improving the performance of devices such as telescopes, cameras and optical sensors, and is used in a wide range of fields including astronomy, vision science, satellite communications and optical imaging.
The progress of adaptive optics technology is mainly due to the improvement of the accuracy of wavefront sensors, the improvement of control algorithms, the development of deformable mirrors and the enhancement of computing power. The continuous improvement of these techniques enables the adaptive optics system to perform distortion correction faster and more efficiently. Future adaptive optics systems are expected to further accelerate response speed and improve correction accuracy by integrating artificial intelligence and machine learning algorithms, while also reducing costs, which will make adaptive optics technology useful in a wider range of applications. The FIS4 four-wave interference sensor will play an important role in this process, measuring the wavefront of light waves in real time and feeding the data back to the deformable mirror assembly to adjust the wavefront in real time, which is particularly useful in the field of space optics and biooptics.
