Microscope with extension of the depth of field by employing a cubic phase plate on the surface of lens

Results in Optics, 2021
An incoherent optical system with wavefront coding extends the depth of field (DOF) by employing a cubic phase plate (CPP). We designed a digital microscope with a CPP in the aperture stop and on the surface of the lens, which extended the DOF.

Depth perception with gaze-contingent depth of field [PDF]

, 2014
Blur in images can create the sensation of depth because it emulates an optical property of the eye; namely, the limited depth of field created by the eye's lens. When the human eye looks at an object, this object appears sharp on the retina, but objects
