High-efficiency scattering media single-pixel correlated imaging based on symmetrically related random phases

Although single-pixel correlated imaging has the capability to capture images in complex environments, it still encounters challenges such as high computational complexity, limited imaging efficiency, and reduced imaging quality under low-light conditions.We innovatively propose a symmetrically related random phase-based correlated imaging method, which reduces the number of required random scattering media, enhances computational efficiency, and mitigates system noise interference.Single-pixel correlated imaging can be completed within 2 min using this approach.The experiments demonstrated that both the constructed dual-path thermal-optical correlated imaging system and the single-path computational correlated imaging system achieved high-quality imaging even under low-light conditions.
