Holography, tomography and 3D microscopy as linear filtering operations
Institute of Physics (May 22 2008)
Microscopy,
Non-Medical
In this paper, we characterize 3D optical imaging techniques as 3D linear shift-invariant filtering operations. From the Helmholtz equation that is the basis of scalar diffraction theory, we show that the scattered field, or indeed a holographic reconstruction of this field, can be considered to be the result of a linear filtering operation applied to a source distribution. We note that if the scattering is weak, the source distribution is ...
What if there were a genie in your microscope?BioOptics World (May 21 2008)
Microscopy
My eyes sweep across a lab rat and I can see everything. Images zoom in and out just because my brain starts thinking of looking at different scales. As my eyes pan along the length of the animal, I watch the trafficking of specific biochemicals, and I know which was which—all without labels, even without any apparent device at all.
Photonic Frontiers: Microscopy Techniques - The quest to see inside living cells is driving new optical microscopyLaser Focus World (May 13 2008)

Microscopes have given scientists vital insight into living things ever since Robert Hooke and Antoni van Leeuwenhoek discovered the microscopic world in the 17th century. Now the quest for better views of living cells is pushing development of new types of optical microscopy that overcome the traditional limitations without sacrificing the advantages of visible light.

Four beams are better than one
optics.org (Apr 11 2008)
Microscopy
At Michelson Diagnostics' booth they believe that more is definitely better - for optical coherence tomography (OCT) imaging anyway. The EX1301 OCT microscope uses four laser beams focused at different depths to provide double the lateral resolution of competing technologies. A laser beam with a wavelength of 1300 nm can be brought to a focus of around 20 µm over a depth of focus of 1 mm. However, by using ...
