The development trend of infrared sensors and their applications in temperature sensors and other industries
Nowadays, infrared sensor technology has been very mature, has been integrated into people's daily life, and is playing a huge role. Before understanding the infrared sensor, first of all, we should understand what is infrared, or infrared light. We know that light is also a kind of radiating electromagnetic wave. According to human experience, it usually refers to the range of light visible to the naked eye from 400nm (violet light) to 700nm (red light) that can be felt by human eyes. . We call the radiation outside the red light and the wavelength between 760nm and 1mm as infrared light. Infrared light is invisible to the naked eye, but we can still feel it through some special optical equipment. Infrared is a kind of light invisible to human eyes, so it has all the characteristics of light. But at the same time, infrared rays also have a very significant thermal effect. All substances above absolute zero that is -273°C can produce infrared rays. So, to put it simply, an infrared sensor is a sensor that uses infrared as a medium for data processing. There are roughly two types of infrared sensors, namely transmissive infrared sensors and reflective infrared sensors. When it is necessary to detect any movement between objects, a transmissive infrared sensor can be used. It is placed between objects. When some objects pass between the objects, the transmission sensor detects the activity and informs the activity. In a reflective sensor, when there is something in front of the reflective sensor, it will detect the activity and information about the activity. With the improvement of science and technology, the development of computer microprocessor technology, the improvement of modern digital signal processing technology, the introduction of new semiconductor materials and the progress of processing and manufacturing technology, infrared sensors have developed rapidly in recent years. According to a forecast by a foreign research institution, the global sales of infrared sensors increased from US$152 million in 2010 to US$286 million in 2016. In recent years, the development trend of infrared sensors is mainly reflected in the following four aspects: First, the use of new materials and processing technologies improves the infrared detection rate of the sensor, increases the response wavelength, and shortens the response time. The pixel sensitivity and pixel density are higher, the anti-interference performance is improved, and the production cost is reduced. For example, a new type of pyroelectric sensitive technology that mixes thin films and ceramics has been introduced on the market, making the sensitive components arrayable. The second is the large-scale and multi-functional sensor. With the development of microelectronics technology and the continuous expansion of sensor application fields, infrared sensors are developing from small and single-function to large-scale and multi-functional. For example, the large-scale infrared sensor developed abroad can not only measure the temperature field, but also obtain the human body detection function that the advanced and small infrared sensor does not have (that is, the position of the individual in the space can be accurately located, even if the human Inactive, can also be identified) or large-scale area security monitoring and other functions, very suitable for applications in home automation, medical care, security protection and other occasions. There is also a more common infrared temperature sensor, which can calculate the surface temperature of the object by measuring the infrared radiation intensity emitted by the target without touching the target, so that the user can conveniently measure the target that is difficult to approach or move. Infrared temperature sensor RS-WD-HW-* is an integrated infrared temperature sensor. The sensor, optical system and electronic circuit are integrated in the stainless steel housing, which is easy to install. The standard thread on the stainless steel housing can be quickly connected to the installation site. , At the same time, there are various options (various types of instruments, large screens, paperless recorder purge protective covers, laser sights, adjustable mounting brackets, etc.) to meet the requirements of various working conditions. In addition, the development of a new multi-spectral sensor has greatly improved the functionality of the infrared imaging array. The third is the intelligence of the sensor. New smart infrared sensors usually have multiple microprocessors built in, with advanced digital signal processing or compensation functions such as Fourier transform, wavelet transform, self-diagnosis function, two-way digital communication and other functions, making the sensor more stable, reliable, and reliable. Performances such as noise ratio and convenience are greatly improved. Fourth is the further miniaturization and integration of sensors. Using on-chip integration technology (including blind cell replacement, non-uniformity correction, partial image processing functions, etc.) and other new device structures and new manufacturing process technologies, in MEMS (micro-electromechanical systems), and even NEMS based on nanotechnology Driven by the electromechanical system), the size of the infrared sensor has been greatly reduced, the power consumption has been greatly reduced, and the integration level has been significantly improved.
At the same time, as the recent research of Rika Sensors shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
