To visualize the phase differences, a technique analogous to Zernike phase contrast in light microscopy (that is, converting phase into amplitude information) needs to be applied in TEM as well.

An on-chip wavefront image sensor capable of measuring phase gradients would benefit a wide variety of applications, including phase contrast microscopy ... when a planar light wave is incident ...

The Center is outfitted with an array of Zeiss and Nikon light microscopes that are equipped for various LM techniques. These techniques include brightfield (transmitted and reflected), phase contrast ...
