Abstract
Imaging through biological tissues requires fast retrieval of beam scanning. Regarding this purpose, the angular memory effect (AME) is a classical optical effect studied and widely applied. However, the imaging range of AME is confined, which relies on the thickness or scattering mean free path of scattering media. To break the finite imaging boundary, we numerically exploit the phase relation in transmission matrix (TM) of weak scattering media, from which a higher-order phase relation named optical phase association (OPA) extends beyond AME. Furthermore, we found that the OPA could enable uniform light focusing across output channels through weak scattering media in simulation. We believe the optical phase association would improve the imaging approaches such as confocal imaging and speckle autocorrelation.
