Non-invasive single-shot imaging through a scattering
layer using speckle interferometry
Optical imaging through complex scattering media is one of the major technical challenges with important applications in many research fields, ranging from biomedical imaging, astronomical imaging, to spatially multiplexed optical communications. Various techniques for imaging though scattering mediums have been proposed and discussed in the past. In this talk, we will discuss a new approach for non-invasive imaging through random scattering medium by speckle interferometry. Principle of this technique lies on exploiting the complex nature of the two point correlation function of the random fields and combining digital holography with correlation optics.
Application of this technique in single shot and lens less correlation holography will be discussed. Possible extension of speckle interferometry to the vectorial random fields will also be covered in this talk.
