The laser light beam is very hazardous for human eyes when you look into the light beam when it is activated, and it can cause loss of sight too. This light can be used to transmit the information over long distances. laser-sensor Pin Configuration and Working Principle Basically, this sens...
Based on the time uncorrelated principle of signals and noise, weak target signals in the noise can be distinguished, and the distance measurement capacity for remote distance measurement is achieved; by the adoption of a semiconductor pumping source laser, high-frequency and multiple-pulse laser ...
To this end we would like to emphasize that the main trust of the present work was only the demonstration of these novel applications of XPS, as a proof-of-principle. Our future work will focus on inves- tigations of charge accumulation and dissipation, and probing photo-excitation effects ...
A backward diode simply works on the quantum tunneling principle. Quantum tunneling is a quantum mechanical method wherever wavefunctions can go through a potential barrier. So the transmission throughout the potential barrier can be fixed and depends on the barrier height & width exponentially. This...
Photodiodes give quick responses and are used where needed to detect quick responses on and off like in optical communication, and optoisolators. The photodiodes are semiconductor devices and work on PN junctions. The photodiode works on the principle of converting the light energy into electric ...
Figure 5. Measuring principle of semiconductor varistor pressure sensor The semiconductor strain gauge is a sensitive element whose resistance value changes correspondingly when under tension or pressure. Attach the strain gauges to the silicon diaphragm and connect them to a Wheatstone bridge. When the...
LASER diode Photodiode Varactor diode Schottky diode Tunnel diode PIN diode etc. Let’s see the working principle and construction of these devices briefly. Zener Diode: The P and N regions in this diode are heavily doped such that the depletion region is very narrow. Unlike a normal diode ...

The Thermistor works on a simple principle: Change in temperature of the Thermistor, leads to a change in its resistance. How does its temperature change? The Thermistor’s temperature can change either due to external factors or due to internal factors. ...
Theworking principle of flow meteris to measure the amount of gas, liquid otherwise streams around the device. These devices work with the same end goal but in different ways. They offer repeatable & accurate flow measurements for different applications likesemiconductorprocessing, process control, et...
