Optical diode application
The PN connecting optoelectronics diode is the same as other types of optical detectors, and it is widely used in equipment such as light -sensitive resistance, sensitivity coupling components, and photoelectric multiplier pipes.They can output the corresponding analog telecommunications signal (such as measuring instruments) or switch between different states of digital circuits (such as control switch and digital signal processing) according to the different state of digital circuits.
Optical diode is also applied in consumer electronics, such as CD players, smoke detectors, and infrared remote control equipment that controls TVs and air -conditioning.For many application products, optoelectronic diode or other optical guide materials can be used.They can all be used to measure light, and often operate in the camera's light meter, automatic adjustment of street lights, etc.
All types of light sensors can be used to detect sudden light, or detect the light inside the same circuit system.Optical diode is often merged with light emitting components (usually luminous diode) to form a module. This module is often called photoelectric coupling component.If so, you can analyze the movement of external mechanical components (such as light cutter) by analyzing the condition of receiving light.Another role of photoelectric diode is to act as an intermediary between analog circuits and digital circuits, so that the two circuits can be coupled through optical signals, which can improve the safety of the circuit.
In scientific research and industry, photoelectric diode is often used to accurately measure light, because it has better linearity than other optical guide materials.
In medical application devices, photoelectric diode also has a wide range of applications, such as X -ray calculator fault imaging and pulse detector.
The PIN connecting optoelectronics diode is generally not used to measure very low light.If a high -sensitivity detector is needed under weak light, the avalanche optoelectronics diode, sensitivity coupling component or photoelectric pipe can be played, such as astronomy, spectrometry, night vision equipment, laser distance meter and other applications.
