An extended depth of field (EDF) microscope that allows for quantitative axial positioning has been constructed. Past work has shown that EDF microscopy allows for features in varying planes to appear sharply focused simultaneously, however an inherent consequence of this is that depth information is lost. Here, a specifically engineered phase plate is used to create a point spread function (PSF) that contains both of the necessary attributes for extended depth of field and quantitative depth mapping. A two-camera solution is used to separate and capture the information for individualized post processing. The result is a microscope that can serve as an essential tool for full 3D, real-time imaging. |
