The ability to image through complex and opaque media is extremely valuable in numerous applications, ranging from astronomical observations through turbulent atmosphere to microscopic imaging in turbid tissues, or surveillance through curtains. Although research progress has been made to recover optical image through various turbid media, the widespread application of the technology is hampered by the recovery speed, requirement on specific illumination, poor image quality and limited field of view.

  

Recently, Prof. Jianying Zhou’s research team affiliated to the State Key Laboratory of Optoelectronic Materials and Technology and the School of Physics at Sun Yat-sen University published a novel optical technique, namely high speed color imaging through scattering media with a large field of view. This technique is successfully implemented through turbid media by taking into account all the factors regarding material response and systematical optical parameters. The added advantage of the technique includes high speed response and optical spectral resolution. Hence it is demonstrated that finger print spectrum and its spatial distribution behind turbid material can be readily readout, allowing, for example, non-intrusive and instant diagnosis of human blood, a vital technique for health issues.
