Description of the photoelectric sensor components
A photoelectric sensor is a device that converts light signals into electrical signals. Its operating principle is based on the photoelectric effect, which occurs when light shines on certain materials, causing electrons within those materials to absorb the energy of photons and triggering corresponding electrical phenomena.
Based on the different phenomena of the photoelectric effect, it is classified into three categories: the external photoelectric effect, the internal photoelectric effect, and the photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, light-sensitive resistors, photodiodes, phototransistors, solar cells, and more. This analysis examines the performance and characteristic curves of these photoelectric devices.
Overview of Optoelectronic Sensors:
Optoelectronic sensors generally consist of two main parts: the processing pathway and the sensing element. Their fundamental principle is based on the photoelectric effect, which converts changes in the measured quantity into variations in optical signals—and then, through the use of optoelectronic components, further transforms these optical signals into electrical ones. The photoelectric effect occurs when light shines on a material, effectively delivering a series of photons, each carrying a specific amount of energy, onto the surface of that material. In this process, the photon energy is transferred to electrons, with an entire photon's energy being absorbed by a single electron at once. As a result, the electron's state changes, triggering a corresponding electrical response in the illuminated object. Typically, the photoelectric effect is categorized into three types:
(1) The phenomenon where electrons are emitted from a material's surface upon exposure to light is known as the external photoelectric effect, examples of which include phototubes and photomultiplier tubes;
(2) The phenomenon where the resistivity of a material changes under light exposure is known as the internal photoelectric effect, seen in devices such as photoresistors and phototransistors.
(3) The phenomenon where an object generates an electromotive force in a specific direction under the influence of light is known as the photovoltaic effect, as seen in devices like solar cells.
Optoelectronic detection methods offer advantages such as high precision, rapid response, and non-contact operation, while also enabling the measurement of multiple parameters. Additionally, these sensors boast a simple structure and come in a wide variety of flexible forms. As a result, optoelectronic sensors are widely used in both detection and control applications.
Optoelectronic sensors are the key components that enable photoelectric conversion in various optoelectronic detection systems—they are devices that transform light signals (including visible and ultraviolet laser light) into electrical signals.
Optoelectronic sensors are sensors that use optoelectronic devices as their conversion elements. They can detect non-electrical physical quantities that directly cause changes in light, such as light intensity, illuminance, radiation-based temperature measurement, and gas composition analysis. Additionally, these sensors can also be used to measure other non-electrical parameters that can be translated into variations in light, including part diameters, surface roughness, strain, displacement, vibration, velocity, acceleration, as well as tasks like object shape recognition and monitoring of operational states. Optoelectronic sensors boast several advantages, including non-contact operation, rapid response times, and reliable performance, which is why they have become widely adopted in industrial automation systems and robotics. Moreover, the continuous emergence of new optoelectronic devices—especially the development of CCD image sensors—has opened up exciting new possibilities for even broader applications of optoelectronic sensors.
