Background:

Dynamic object imaging through scattering media is challenging due to light distortion.
Traditional methods struggle with high compression ratios and complex scattering environments.
Compressive sensing offers potential but requires sophisticated reconstruction algorithms.

Purpose of the Study:

To develop an end-to-end deep learning model for reconstructing multiple frames from a single snapshot.
To enable high-speed imaging of dynamic objects in unknown, time-varying scattering conditions.
To achieve significant data compression (up to 8X) while maintaining high image fidelity.

Main Methods:

Integration of a coded aperture compressive temporal imaging system.
Development of a specialized transformer-based convolutional neural network (CNN) for demultiplexing and reconstruction.
Utilizing a dual-input CNN architecture incorporating speckle patterns and their autocorrelations.

Main Results:

Successful reconstruction of up to eight frames from a single snapshot.
Demonstrated compression ratio of up to 8X in both simulations and experiments.
Achieved high reconstruction quality and accuracy, validated by ablation studies.
The dual-input CNN significantly enhanced reconstruction accuracy compared to single-input models.

Conclusions:

The proposed deep learning model effectively reconstructs dynamic scenes from compressed single-snapshot data.
The integration of coded aperture imaging and advanced CNNs offers a powerful solution for high-speed imaging through scattering media.
The dual-input CNN approach is crucial for maximizing reconstruction accuracy in complex scattering environments.
