Abstract: A lens-free single-frame phase recovery method based on partially coherent light-emitting diode illumination. The method is implemented in a lens-free on-chip microscopy experiment system. Only a single-color patch LED light source is used for illumination, and a single in-line hologram is collected. High-resolution and high signal-to-noise-ratio phase information of an object is then directly recovered by means of a multi-wavelength iteration phase recovery method in combination with a dynamic phase support constraint. By means of the method, the capability of rapid and long-time lens-free on-chip single-frame phase recovery can be given without the need for complex transformation of a conventional lens-free on-chip microscope. The structure of a microscopy system includes a light source (1), a sample (2) and a sensor (3).
