Scanned beam medical imager

SPIE Proceedings, 2004
We report on a conceptual design and feasibility demonstration for a scanned beam endoscope, with advantages over present CCD imaging technology in image resolution and quality, light source power, and package diameter. Theoretical calculations were made by optical modeling and finite element analysis of the performance projected for a design meeting ...

Wideband and beam-scanning reflectarrays

2015 International Workshop on Antenna Technology (iWAT), 2015
Reflectarray antenna attracts growing interests in the last decades. This paper presents some recent developments on reflectarray antennas, namely, a broadband reflectarray antenna and a beam-scanning reflectarray antenna. They demonstrate great potential in satellite communications, remote sensing, and radar applications.

Scanning Techniques With Light Beams

Information Display, 1966
Summary A survey and analysis of methods of optical deflection of light beams is presented in this paper. Coherent light beams could be used for small or large screen displays similar to the electron beam magnetic or electrostatic deflection, if light beam deflection methods are available with adequate deflection angle.

Comparison of Beam Scanning Systems

1983
Present day ion implanters provide uniform distribution of energetic ions into target materials, utilizing one or two of the basic beam scanning techniques; electrostatic, magnetic, and mechanical. Each beam scanning technique has physical limits and characteristics which affect its successful use in an ion implanter for semiconductor processing.

Signals Excited by the Scanning Beam

1976
The main part of this book deals with transmission electron microscopy of thin foils. In this chapter we illustrate very briefly with a few examples the possibilities of the scanning electron microscope (SEM). The electron beam excites electromagnetic waves and electron signals from a thin surface layer of a target in a wide energy range from fractions
