What is lidar???
Light detection and ranging(LIDAR) is an optical Remote Sensing Technology that can measure the distance to an object or surface.

It is similar to Radar, but it incorporates laser pulses rather than radio waves.

RADAR Radio Detection And Ranging

Radio Detection And Ranging ,in short RADAR relies on sending and receiving electromagnetic radiation, usually in the form of radio waves (see Radio) or microwaves. Electromagnetic radiation is energy that moves in waves at or near the speed of light. The characteristics of electromagnetic waves depend on their wavelength. Gamma rays and X rays have very short wavelengths.

Visible light is a tiny slice of the electromagnetic spectrum with wavelengths longer than X rays, but shorter ....etc

Abstract
Most device drivers have one ulterior motive and one target to achieve - deliver the maximum using the minimum. No matter how stable or feature rich a device driver might be, if it cannot perform in terms of high throughput and low CPU utilization, it is as good as any other run of the mill driver.The objective of this topic is to use the thinking out of the box concept and expose techniques, which go beyond just good programming principles to get that extra edge which can put your next driver into the elite group of high perform ....etc

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

ABSTRACT

Light Detection and Ranging (LIDAR) have recently become the technologies of choice in mass production of Digital Elevation Models (DEMs), Digital Terrain Models (DTMs), and Triangulated Irregular Networks (TINs), referred to generically hereafter as DEMs. This paper presents lessons learned from LIDAR projects to date in various states. It addresses opportunities presented by LIDAR for generating DEMs as articulated by various user groups in the National Height Modernization Study. Finally, it summarizes actions required by th ....etc

OPTICAL devices

INTRODUCTION
Explosive information demand in the internet world is creating enormous needs for capacity expansion in next generation telecommunication networks. It is expected that the data- oriented network traffic will double every year. Optical networks are widely regarded as the ultimate solution to the bandwidth needs of future communication systems. Optical fiber links deployed between nodes are capable to carry terabits of information but the electronic switching at the nodes limit th ....etc

RANGING & LANDING SYSTEMS


The VHF Omni-directional Radio Range is the abbreviations for which are VOR and Omni , enables a pilot to determine the direction of his aircraft from any position to or from a VOR beacon

range

VOR is a Very High Frequency (VHF) navigation aid which operates, its ground to air range is limited to line of sight reception which is typical of VHF transmission. The range achieved is dependent, therefore, on the siting of the VOR beacon with relat ....etc

Abstract:

In this paper, analysis of CDMA network with Optical Amplifiers has been done. As the optical amplifier provides gain as well as has nonlinear characterstics, gain is expected due to signal amplification as well as operation of SOAs as limiter due to gain saturation. In this paper results have been computed for with different SOA placements in a typical star topology employing CDMA. The results show that in a star topology network employing CDMA, placement of SOAs before CDMA decoder does provide benefit due to g ....etc
