Hot-Air Convection Atmospheric Turbulence Simulator 1.0

Atmospheric Coherence Length: 1 - 25cm Phase Simulation Accuracy: 1/8λ Coherence Length Simulation RMS [@（r0=1cm）]: 0.20

This product rapidly and quantitatively simulates atmospheric-turbulence effects on propagating beams: intensity scintillation under finite-aperture reception, angle-of-arrival fluctuations, beam spreading, spot wander, phase distortion, and degraded coherence. Configurable parameters include propagation distance, refractive-index structure constant, and atmospheric coherence length; outputs are monitored. It supports functional verification and performance testing of atmospheric laser systems. Software and interface: Three modes are available. 1. Enter atmospheric coherence length directly; turbulence phase screens are generated in real time. 2. Generate phase screens using Zernike polynomials for turbulence simulation. 3. Enter atmospheric parameters; the software calculates coherence length and simulates turbulence using mode 1.

Atmospheric Refractive Index Structure Constant: 10km: ≥10⁻¹⁴m^(-2/3) (moderate-to-strong turbulence); 1km: ≥ 10⁻¹²m^(-2/3) (strong turbulence) Atmospheric Refractive Index Structure Constant: 10km: ≥ 10⁻¹⁴m^(-2/3) (moderate-to-strong turbulence); 1km: ≥10-12m-2/3 (strong turbulence) Atmospheric Coherence Length: 1-40cm

The liquid-crystal atmospheric turbulence simulator reproduces major effects of laser propagation through Earth's atmosphere, including intensity scintillation, angle-of-arrival fluctuations, and spot drift. Configurable inputs include altitude, elevation angle, propagation distance, time, and location. Outputs can be monitored and compared with theoretical values. It supports functional verification and performance testing of various atmospheric-channel laser systems. Several key technical challenges have been overcome, and the product has entered the pilot stage.
