| Diffraction of light is a fundamental phenomenon in optics, arising from the wave nature of light itself. Discovered by Italian scientist Francesco Maria Grimaldi back in 1660, diffraction is usually characterized by the bending of light waves around the edges of obstacles or small openings as light travels through them. One of the most notorious effects of diffraction in optical systems is information loss due to challenges in the reconstruction of the diffracting light wave. On the one hand, diffraction has become a fundamental limiting factor in modern-days microscopy, by dictating spatial resolution of optical systems. On the other hand, the same limitation has been studied and exploited for both optical and digital information encryption and compression technologies.
In this research we have dived into the information loss mechanism caused by diffraction of light and explored various inhibitors in modern super-resolution microscopy. By addressing spatial resolution enhancement as Fourier domain tessellation challenge, we introduced a patterned illumination methodology coupled with innovative image reconstruction approach, allowing unprecedented combination of spatial and temporal resolution for live cells microscopy. In parallel, leveraging our ability to access spectral content beyond an optical system’s diffraction limit, we proposed a method for utilizing diffraction induced information loss for optical encryption applications. |
