A simple-to-use analytical guide to optical sectioning with patterned illumination

Illumination patterning techniques for optical sectioning in a wide-field microscope allow for maintaining good temporal resolution while improving image quality. Among these, two techniques are particularly widespread: structured illumination and line-confocal imaging. Until now, however, the relationship between the quality of optical sectioning and illumination parameters (wavelength, numerical aperture, illumination pattern) was not straightforward and relied on complex numerical calculations.

By deriving simple analytical formulas and comparing them to experimental data, this new work published in Biomedical Optics Express permits to accurately predict and optimize the quality of the axial sectioning and to determine which approach will provide the best images depending on the type of sample being studied, in particular in terms of signal-to-noise ratio.
