Multiple wavelength diffractive imaging - X
... Fig. 4!c", showing excellent agreement with the image in Fig. 4!a". The MEM refinement produces a much smoother image but some of the detail in the sample is lost, indicating that the algorithm is probably underfitting the data due to an overestimate of the noise level. The faint crosslike structure ...

3D differential interference contrast microscopy using synthetic
... Differential interference contrast microscopy techniques visualize a specimen of weak contrast by converting the field gradient of a light into intensity variation. It has served as a label-free tool to image biological specimens.1,2 However, the intensity in the DIC image is determined by the coupl ...

Wollaston and Nomarski Prisms
... Birefringent Wollaston and/or Nomarski prisms are inserted in the optical pathway with their shear axis oriented at a 45-degree angle (northwest to southeast) to the polarizer and analyzer. The prisms are composed of two precisely ground and polished wedge-shaped slabs produced from high-grade optic ...

... An additional characteristic of X-PEEM is the high surface sensitivity that is inherent with the detection of secondary electrons. In most materials, the low kinetic energy of the secondaries (typically <10 eV) limits the electron escape depth to 2 – 5 nm. This can be an advantage in some cases, how ...
