Quasianamorphic optical imaging system with tomographic reconstruction for electron beam imaging

Review of Scientific Instruments, 2007
We have developed a quasianamorphic optical tomography system coupled to a streak camera to provide continuous recording of the electron beam profile of an intense, long-pulse induction accelerator. A tomographic reconstruction method based on a maximum-entropy algorithm is used to reconstruct the images.

Electron optical analysis of a retarding Wien filter for electron spectroscopic imaging

Review of Scientific Instruments, 1993
A new Wien filter has been designed for electron spectroscopic imaging. The shape of the electrodes and the magnetic pole pieces of the filter has fourfold symmetry and therefore the Wien condition giving a straight optical axis is satisfied even in the fringing field region.

Optical performance of electronic imaging systems for the colon

Gastroenterology, 1989
Electronic (video) endoscopes are a significant new development in gastroenterology, offering the potential of enhanced teaching and permanent storage of pictorial data. The primary concern of gastroenterologists is the resolution and color performance of these instruments, as these parameters have important bearings on the ability to discern ...
