17.7 Summary of Important Points
1. In structured illumination, a pattern is imposed on the incident light via
a mask, such as a Ronchi ruling, or interference of one or more coherent
sources.
2. In most cases the entire field is not illuminated, making several camera
acquisitions necessary per axial position.
3. Optical sectioning is a nondestructive way to obtain a 3-D image of
a specimen.
4. Using three image acquisitions, SIM is capable of matching the axial
resolution of the confocal microscope.
5. All forms of SIM are dependent on computer processing to compose
a final image from several separate acquired images.
6. Remnants of the illumination grid ...
