A spectrophotometer is a device that uses a light source of all visible light along with ultraviolet and infrared ranges. Diffraction grating then separates the light by wavelength. The light

CHAPTER 1 — BASIC RADAR PRINCIPLES AND GENERAL CHARACTERISTICS INTRODUCTION The word radar is an acronym derived from the phrase RAdio Detection And Ranging and applies to electronic equipment designed for detecting and tracking objects (targets) at considerable distances. The basic principle behind radar is simple - extremely short bursts of radio energy (traveling at the speed of light) are transmitted‚ reflected off a target and then returned as an echo. Radar makes use of a phenomenon

Multiple-Input Multiple-Output Wireless Communication Systems Using Antenna Pattern Diversity Liang Dong‚ Hao Ling‚ and Robert W. Heath‚ Jr. Department of Electrical and Computer Engineering The University of Texas‚ Austin‚ TX 78712 Abstract— Multiple-input multiple-output (MIMO) wireless communication systems employ multiple transmit and multiple receive antennas to obtain significant improvement in channel capacity. However‚ the capacity is limited by the correlation of subchannels in non-ideal

|LASER ALIGNMENT THEORY Modern optical metrology uses precise lines and planes in space from which measurements are made. Because this method creates these features using light it has become known as optical tooling. The 35 year old historical development and current technology of laser instrumentation as used in optical tooling is discussed in detail. This includes the how the measurements are made‚ applications‚ and the technology of alignment lasers and position sensing targets developed for

Photography Photography is the art‚ science and practice of creating durable images by recording light or other electromagnetic radiation‚ either chemically by means of a light-sensitive material such as photographic film‚ or electronically by means of an image sensor.[1] Typically‚ a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. The result in an electronic image sensor is an electrical

H2O vs H2O2) * Law of conservation of mass: atoms cannot be created or destroyed during a chemical reaction
