Stereoscopic Passive Millimeter-Wave Imaging and Ranging

Thomas L thi and Christian M tzler, Senior Member, IEE


Abstract

This paper presents the first stereoscopic range measurements
at a wavelength of 3.3 mmand discusses the accuracy of
this new method. The synthesis of passive millimeter-wave imaging
and stereoscopy combines the advantages of both principles, naturally
looking high-contrast images and superior poor-weather performance
(compared to visible and infrared wavelengths), as well
as the pas ....etc

Non Visible Imaging

Near infrared light consists of light just beyond visible red light (wavelengths greater than 780nm). Contrary to popular thought, near infrared photography does not allow the recording of thermal radiation (heat). Far-infrared thermal imaging requires more specialized equipment. Infrared images exhibit a few distinct effects that give them an exotic, antique look. Plant life looks completely white because it reflects almost all infrared light (because of this effect, infrared photography is commonly used in aerial photog ....etc

See-Through Walls: Motion Tracking Using Variance-Based Radio Tomography Networks


INTRODUCTION

THIS paper explores a method for tracking the location of a
person or object behind walls, without the need for an
electronic device to be attached to the target. The technology
is an extension of radio tomographic imaging , which is
so-called because of its analogy to medical tomographic
imaging methods. We call this extension variance-based radio
tomographic imaging (VRTI ....etc

Tomographic imaging of electrically large objects in 2-D and 3-D environments using ultra-wideband (UWB) sensor arrays is described. Object cross-section electric properties is the most difficult part to model.Different industrial, medical, and security applications use microwave signals to penetrate and sense light opaque materials with reasonable spatial resolution.Increased level of spatial resolution and materialelectrical parameter measurement accuracy of Wideband signals, such as those produced with ultra-wideband (UWB) systems makes it ....etc

terahertz imaging seminar report

Terahertz imaging is an emerging and significant nondestructive evaluation (NDE) technique used for dielectric (nonconducting, i.e., an insulator) materials analysis and quality control in the pharmaceutical, biomedical, security, materials characterization, and aerospace industries.It has proved to be effective in the inspection of layers in paints and coatings,detecting structural defects in ceramic and composite materials and imaging the physical structure of paintings and manuscripts. The use of THz waves ....etc

Magnetic resonance imaging (MRI)

Abstract
Magnetic resonance imaging (MRI) is a noninvasive method for producing three-dimensional tomographic images of the human body. MRI is most often used for the detection of tumors, lesions, and other abnormalities in soft tissues, such as the brain.
Several techniques for automatically segmenting brain tissues in MRI scans of the head have recently been developed. One goal of segmentation is to automatically or semi-automatically detect lesions in the brains ....etc

INTRODUCTION

When an object moves into the area of a wireless network, links which pass through that object will experience shadowing losses. This paper explores in detail the use of shadowing losses on links between many pairs of nodes in a wireless network to image the attenuation of objects within the network area. We refer to this problem as radio tomograph ....etc
