Hall effect sensor work is a type of magnetic sensor. A Hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field. In 1879 Edwin Hall discovered that: ‘when a conductor or semiconductor with current flowing in one direction was introduced perpendicular to a magnetic field a voltage

Point to Point Links The simplest transmission link is a point to point links line that has a transmitter on one end and a receiver on the order. This type of link places the least demand on optical fiber technology and thus sets the basis for examining more complex system architectures1-10. The design of an

Ultrasonic Inspection This method is used to find internal defects by using ultrasonic inspection sound waves. Very minute defects such as cracks, porosity, blowholes etc. can be accurately detected in castings. Sound waves can pass through solids without any absorption. It can also be reflected from a surface. Hence, ultrasonic waves are used in this

Radiographic Inspection Radiography (X-ray) is an NDT method used to radiographic inspection material and components using the concept of differential adsorption of penetrating radiation. Each specimen under evaluation will have differences in density, thickness, shapes, sizes or absorption characteristics. Thus, the different amount of radiation is absorbed. The unabsorbed radiation that passes through the part

Liquid Penetrant Inspection Liquid penetrant inspection is used on nonporous metal and nonmetal components to find material discontinuities that are open to the surface and may not be evident to normal visual inspection. The dye penetrant method is frequently used for the detection of surface breaking flaws in non-ferromagnetic materials. The basic purpose of penetrant

Radio over Fiber Links One application of RF radio over fiber technology is in broadband wireless access networks for interconnecting antenna base stations (BSs) with the central controlling office. Image shows the basic network architecture for such a scheme. Here a collection of antenna base stations provide wireless connectivity to subscribers by means of millimeter-wave

Analog Link In telecommunication networks the trend has been to analog link telephone exchanges with digital circuits. A major reason for this was the introduction of digital integrated-circuit technology which offered a reliable and economic method of transmitting both voice and data signals. Since the initial applications of fiber optics were to telecommunication networks, its

Penalty Power The analysis in this post assumed that the optical power falling on the photodetector is a clearly defined function of time within the statistical nature of the quantum detection process. In reality, a number of Penalty power signal impairments that are inherent in optical fiber transmission systems can degrade the link performance. When
