Optical coherence tomography (OCT) is an optical signal acquisition and processing method allowing extremely high-quality, micrometer-resolution, three-dimensional images from within optical scattering media (e.g., biological tissue) to be obtained. In contrast to other optical methods, OCT, an interferometric technique typically employing near-infrared light, is able to penetrate significantly deeper into the scattering medium, for example 3 deeper than its nearest competitor, Confocal microscopy. Depending on the use of high-brightness and ....etc

ABSTRACT

Smart or intelligent materials are materials that have the intrinsic and extrinsic capabilities, first, to respond to stimuli and environmental changes and, second, to activate their functions according to these changes. The stimuli could originate internally or externally. Since its beginnings, materials science has undergone a distinct evolution: from the use of inert structural materials to materials built for a particular function, to active or adaptive materials, and finally to smart materials with more acute recognitio ....etc

1. INTRODUCTION
Deep space exploration and utilization are all along the dreams of human beings. The exploration and utilization of the deep space are all along the dreams of human beings. Since the Soviet Union began to explore the moon by using moon-1 in January 1959, there has existed drastic competition in the area of deep space exploration and utilization among the countries all over the world, especially among the United State, Russia and some countries in Europe. Besides the technologies of launching and controlling ....etc

A technical seminar report on
Synthetic aperture radar
Synthetic-aperture radar (SAR)
It is a form of radar in which multiple radar images are processed to yield higher-resolution images than would be possible by conventional means. Either a single antenna mounted on a moving platform (such as an airplane or spacecraft) is used to illuminate a target scene or many low-directivity small stationary antennae are scattered over an area near the target area. The many echo waveforms received at the different antenna position ....etc

1. INTRODUCTION
Today data storage is dominated by the use of magnetic disks. Storage densities of about more than 5 Gb/cmhave been achieved. In the past 40 years areal density has increased by 6 orders of magnitude. But there is a physical limit. It has been predicted that superparamagnetic effects- the bit size at which stored information become volatile as a function of time- will limit the densities of current longitudinal recording media to about 15.5 Gb/cm2.In the near future century nanometer scale will pre ....etc

Optical Coherence Tomography (OCT)

Introduction
Optical Coherence Tomography (OCT) is an imaging technique that is similar in principle to ultrasound, but with superior resolution. It relies on exposing a sample to a burst of light and then measuring the reflective response from different depths and is therefore capable of scanning non-invasively beneath the surface of the sample. In ultrasound imaging, it is relatively easy to measure the time delay of each reflected packet. However, for light pulses, interferometry must be used to measure ....etc

Abstract
Destructive and non-destructive methods have been used for the determination of micro-traces of antimony in high-purity silicon powder. The destructive method was based on sub-stoichiometric radio-activation analysis with solvent extraction using BPHA and cupferron as organic reagents. The antimony contents in high-purity silicon can be determined by the proposed method.
A new non-destructive method was developed for the detection of refrigerant leakage at an evaporator's inflow. Nitrogen and oxygen gas were suc ....etc
