Abstract
The disturbance of atmospheric turbulence during laser transmission is a major problem in the field of high-energy laser transmission and communication. Fast and real time wavefront sensing is one of the key technologies in adaptive optical systems. For laser emission or communication systems with relatively smaller optical apertures and transmission distances, atmospheric aberration is mainly composed of low-order Zernike modes with weak intensity. Traditional Hartmann wavefront sensor works by regional segmentation and reconstruction of the wavefront plane, which need complicated matrix calculation, inducing considerable time delay. Its application in laser wavefront sensing can be technically sophisticated and redundant. Holographic modal wavefront sensing technology takes advantage of parallel modal detection method to obtain the intensity of specific modes of aberrations carried by the laser directly. With benefits of higher speed, smaller time delay, and compact system structure, it may be more suitable for atmospheric laser wavefront sensing. Here, we carried out simulation research on holographic modal wavefront sensor and its application in atmospheric laser wavefront sensing, the measuring accuracy and validation frontier of this technology are analyzed. The result provided informative support on high speed laser aberration sensing and correction.
