To enhance the efficiency and theoretical understanding of ghost imaging techniques.

Main Methods:

Proposing a sequential-deviation ghost imaging method.
Utilizing conditional averaging of reference patterns without ensemble average comparison.
Validating the technique through both simulations and experimental results.

Main Results:

Achieved real-time reconstruction of positive-negative images.
Demonstrated high image quality comparable to differential ghost imaging.
Significantly improved real-time performance by eliminating the need for ensemble average comparison.

Conclusions:

The sequential-deviation ghost imaging approach offers a viable method for efficient, real-time image reconstruction.
This technique enhances the practical applicability of ghost imaging by reducing acquisition time.
The study contributes to the theoretical framework of ghost imaging, particularly in generating positive-negative images.
