ptical imaging beyond conventional limits——An introduction to scattering light imaging techniques

Optical imaging is an important means for mankind to acquire information.However, in the presence of scattering it is difficult to obtain good quality images by conventional imaging methods, for example, in astronomy, bio-medical microscopy, and even daily observation.This is not only a fundamental optics issue but also a long-standing problem that has yet to be solved. Thanks to the development of science and technology, great breakthroughs have been made in recent years. In this letter, the latest progress in the technique of imaging through scattering media by light field modulation and de-convolution methods is described and discussed.
