Fast optical high-resolution imaging through scattering medium based on virtual synthetic aperture model

High resolution real-time optical imaging through macro-scale scattering medium is challenging in applications. Based on prior spatiotemporal characteristics, existing methods have improved the imaging performance of simple scattering scenarios. Here, we introduce a virtual synthetic aperture model (VSAM) into optical scattering imaging, which focuses on real-time imaging with high resolution and robustness. Our experiments are conducted under the complex scenarios: imaging static or moving targets through acrylic plates or fog. Even though the exposure time is 0.488ms/pixel and average photon counts are less than 4, the proposed method can successfully reconstruct the target located at 1.5m away from acrylic plates or moving with 1m/s. Furthermore, for the fog with one-way optical thickness greater than 6.5 and spatial thickness ∼50cm, our method is also applicable. The experiments indicate that the proposed method without prior knowledge outperforms the related methods in terms of resolution and scene robustness, which significantly benefits its application.
