Optimal Concentration of Light in Turbid Materials [PDF]
, 2010 In turbid materials it is impossible to concentrate light into a focus with conventional optics. Recently it has been shown that the intensity on a dyed probe inside a turbid material can be enhanced by spatially shaping the wave front of light before it

Tuning Knobs for the NLC Final Focus
, 2002 Compensation of optics errors at the Interaction Point (IP) is essential for maintaining maximum luminosity at the NLC. Several correction systems (knobs) using the Final Focus sextupoles have been designed to provide orthogonal compensation of linear ...

Full-field hard x-ray microscopy with interdigitated silicon lenses [PDF]
, 2015 Full-field x-ray microscopy using x-ray objectives has become a mainstay of the biological and materials sciences. However, the inefficiency of existing objectives at x-ray energies above 15 keV has limited the technique to weakly absorbing or two ...

Optical microscope illumination analysis using through-focus scanning optical microscopy [PDF]
Optics Letters, 2017 Misalignment of the aperture diaphragm present in optical microscopes results in angular illumination asymmetry (ANILAS) at the sample plane. Here we show that through-focus propagation of ANILAS results in a lateral image shift with a focus position.

Ray pencils of general divergency
African Vision and Eye Health, 2009 That a thin refracting element can have a dioptric power which is asymmetric immediately raises questions at the fundamentals of linear optics. In optometry the important concept of vergence, in particular, depends on the concept of a pencil of rays ...
