Abstract
Realizing high-quality object reconstruction in complex and dynamic scattering environments is a challenge, especially in highly dynamic scattering environments. Scaling factors can be considered to be constant in a static environment. A highly dynamic scattering environment can result in the changed scaling factors. In this paper, we report a high-quality object reconstruction method using Hadamard-based single-pixel measurement in highly dynamic scattering environments. In the proposed method, the sequence of Hadamard patterns is randomly ordered, and then the Hadamard patterns are applied to illuminate an object. The wave passes through a dynamic and turbid water tank. In this case, randomly changed scaling factors can be obtained. A temporal correction method is applied to eliminate the randomly changed scaling factors in single-pixel intensity measurements. After the temporal correction, high-quality object reconstruction is realized in highly dynamic scattering environments. Experimental results are presented to demonstrate validity of the proposed method.
