Usage of time multiplexing super resolution for imaging through scattering medium

This paper presents an extension of time multiplexing super-resolution imaging concept to allow imaging through scattering medium. The presented concept includes laser illuminating an object through a diffuser. The technique performs time multiplexing super-resolved imaging through this diffuser while using the unknown speckle pattern the diffuser projects on the imaged object to enhance the resolution at which the object is imaged. Thus, unlike in conventional case where imaging through a diffuser or other scattering medium destroys the imaging resolution, here the speckle pattern the diffuser generates assists in performing super-resolved imaging. Experimental results demonstrate the efficacy of the approach, showing significant improvement in image quality and resolution.
