Atmospheric Turbulence Simulation Experimental System
The atmospheric turbulence simulation experimental system is built upon a spatial light modulator (SLM) to create a platform for simulating atmospheric turbulence conditions. By leveraging Kolmogorov’s statistical theory of turbulence and the power spectral density method, it generates dynamically adjustable turbulent phase screens. The system supports adjustment of subharmonic orders, enabling the creation of random phase screens that accurately reflect the statistical characteristics of turbulence. The software integrates a multidimensional parameter-control module that encompasses key variables such as phase-screen resolution and size, atmospheric coherence length (r0), inner and outer turbulence scales (l0 and L0), beam wavelength, beam waist radius, and propagation distance, thereby facilitating fine-grained simulation of turbulence intensity and propagation scenarios. Real-time loading of phase screens onto the SLM enables wavefront modulation, while the system also provides synchronous support for visual analysis of phase screens, import and export of image files, and data storage, thus offering a high-precision experimental environment for research on laser propagation under atmospheric turbulence interference and for validation of adaptive-optics algorithms.
