WebJun 20, 2011 · The optical sectioning performance is typically measured by focusing through a surface mirror that models an infinitely thin structure in z. This method is (comparably) easy and is used to examine the performance of … WebNov 1, 2006 · This paper describes a new implementation of the light sectioning method with the latest structured lighting and machine vision techniques for this purpose. As a reference, a laser profilometer is used. The data from the light sectioning method and from the profilometer are highly correlated.

Bright-field light microscopy Beyond increasing numerical aperture, there are few techniques available to improve optical sectioning in bright-field light microscopy. Most microscopes with oil immersion objectives are reaching the limits of numerical aperture possible due to refraction limits. Differential interference … See more Optical sectioning is the process by which a suitably designed microscope can produce clear images of focal planes deep within a thick sample. This is used to reduce the need for thin sectioning using instruments such as … See more In an ideal microscope, only light from the focal plane would be allowed to reach the detector (typically an observer or a CCD) producing a clear image of the plane of the sample the … See more The primary alternatives to optical sectioning are: • Thin sectioning of the sample, for example as used in histology. • Tomography, which is particularly well developed for transmission electron microscopy. See more WebFiguring out recessed lighting spacing requires a bit of measuring and some simple math. A good general rule for placement is to divide the height of the ceiling by two.
