Imaging device for correcting and reconstructing target image in scattering medium using multiple scattering tracing algorithm based on reflection matrix and method thereof

An imaging device, comprising:

• a light source configured to make light incident on a target object by passing through a scattering medium and multiple scattering components within the scattering medium;
• a detector configured to detect light returned after the incident light transmits and reflects the multiple scattering components of the target object;
• a reflection matrix measurer configured to measure a time-resolved reflection matrix reflecting multiple scattering trajectories based on the multiple scattering components based on the returning light;
• an algorithm processor configured to obtain an incident transmission matrix and a reflection transmission matrix by numerically iteratively accessing a plurality of phase planes approximated from the scattering medium according to a multiple scattering tracing algorithm and to obtain an object reflection matrix by reflecting inverse matrices of the obtained incident transmission matrix and the obtained reflection transmission matrix into the measured time-resolved reflection matrix;
• and
• an image processor configured to acquire an image in which multiple scattering distortion is corrected according to the multiple scattering trajectory based on the obtained object reflection matrix.
