ABSTRACT.A new wavefront sensing approach, derived from the successful curvature wavefront sensing concept but using a nonlinear phase retrieval wavefront reconstruction scheme, is described. The ...

Recent developments in transmission gratings have dramatically increased application areas for transmission gratings. Historically, diffraction gratings have been produced mainly as reflection ...

Due to the inhomogeneity of biological tissue and the impact between photons and microscope particles, photons are inevitably scattered and diverged from the incident direction when traveling in the ...
