Usage of turbulence for superresolved imaging.
We have used the turbulent flow of hot air to improve the diffraction limits of resolution in an imaging system. A time-multiplexing approach was applied and used the turbulent flow near the object to encode its spatially high frequencies. The turbulent perturbations were extracted and numerically implemented to decode the high-resolution image. Experimental verification demonstrated the proposed concept.
