Polarized light fields contain more information than simple irradiance and such capabilities provide an advanced tool for underwater imaging. We used a Monte Carlo technique to simulate the vector point spread function for a broad range of water parameters from clear to turbid coastal waters. We also analyzed the impact of light scattered by suspended particles between the target and the camera on the polarized image together with the light from the target. This knowledge is expected to contribute to solutions of the inverse problem of the restoration of the target polarization characteristics from its underwater image.
