It’s relatively easy to understand how optical microscopes work at low magnifications: one lens magnifies an image, the next magnifies the already-magnified image, and so on until it reaches the eye ...

Microscope lenses are typically made either by grinding and polishing glass discs, or pouring polymers into molds – both techniques can be quite involved, which is reflected in the price of the ...

Researchers have redesigned the concept of a microscope, by removing the lens, to create a system small enough to fit in the palm of a hand, but powerful enough to create 3-D tomographic, or sectional ...

Figure 1: Partially coherent lens-free on-chip microscope. In addition to temporal-coherence requirements, spatial coherence of the illumination is also critical in lens-free holographic microscopy ...

Those of you who have suffered through my writing before will know that I have a thing for imaging. A paper that offered experimental results on a new super-resolution technique was like offering me ...
