Understanding Depth of Field and Depth of Focus in Microscopes

WebDepth-of-Field. When observing an object with a lens, the object is most clearly viewed when it is at the focal point of the lens. If the distance between the lens and the object is slightly varied, then there is a range or tolerance in which the object can still be clearly observed. This range is known as the depth-of-field (DoF). WebA microscopy specific imaging model is formalized, a total variation regularized deconvolution approach is experimentally demonstrated, and results are compared to the Wiener filter. The depth of field of an optical system can be extended through a combination of point spread function (PSF) engineering and image processing.
