A laser diode is a semiconductor device that emits coherent light through the process of stimulated emission. It operates similarly to a light-emitting diode (LED) but produces a focused, monochromatic, and coherent beam of light. The emitted light waves have the same wavelength, frequency, and phase. The laser diode was invented by Theodore H. Maiman, […]

What is a Sensor? Types of Sensors, Classification & Applications
Let’s see various types of sensors within their classification and Applications. A sensor is a device or component that detects changes in its environment and converts those changes into an electrical signal or another form of readable data. Sensors are used in various applications to monitor, measure, or control processes, equipment, or environmental conditions. They […]
