Holographic Microscopy
“Specifically, the researchers [in Korea] devised a method to preferentially select single-scattered waves by taking advantage of the fact that they have similar reflection waveforms even when light is input from various angles. This is done by a complex algorithm and a numerical operation that analyzes the eigenmode of a medium (a unique wave that delivers light energy into a medium), which allows the finding of a resonance mode that maximizes constructive interference (interference that occurs when waves of the same phase overlap) between wavefronts of light. This enabled the new microscope to focus more than 80 times of light energy on the neural fibers than before, while selectively removing unnecessary signals. This allowed the ratio of single-scattered waves versus multiple-scattered waves to be increased by several orders of magnitude.” MORE
