Our approach to extending the depth of field utilizes the concept of point spread function (PSF) engineering to greatly increase the axial range clearly imaged in a single exposure. The basic concept ...

What is depth of field? The depth of field in an image is the distance between the parts that appear in focus. When there's a big distance between the things that look crisp and sharp, it's known ...
