Blind diffractive modulation for scattering-resilient single-pixel complex-field imaging

For robust single-pixel wavefront reconstruction through scattering media, we present a single-pixel blind modulation diffractive imaging that integrates multi-distance diffractive encoding with statistically constrained alternating projection. By jointly retrieving the target wavefront and modulation field under unknown scattering, the method achieves stable convergence and effective disentanglement of scattering background. Support-constrained retrieval and correlation-guided spectrum demodulation enhance reconstruction fidelity and robustness. Experiments confirm reliable complex-amplitude recovery under controlled scattering, demonstrating robustness and potential scalability for multimodal scattering scenarios.
