A new study published in Nature Communications by the research group of Professor Wonshik Choi at the Department of Physics at Korea University demonstrates a lensless, Fourier holographic imaging fiber endoscope that performs label-free imaging of unstained biological tissues. This ultrathin fiber endoscope performs faster and provides a more accurate diagnosis than previous methods.
