Infrared detector really came into view, because we are in some public **** occasions, such as supermarkets, hospitals to go in before going in to measure the body temperature in advance, work off work, in and out to do, this is for the prevention and control of epidemics, people did not understand this thing before, the family will not be prepared for this kind of thing, because there is not much use, But now every day to measure it! It will be of great use.
The working principle of the infrared thermometer is based on his electronic components of the energy emitted by the aggregation of human skin, generally speaking, is the location of the wrist child inside the position according to the proportion of energy reflected back to determine the size of the temperature value, it can only go to detect the body surface temperature, the temperature of the surface of the object, and it is largely affected by the environment, so most of the time, it is in the indoor use of outdoor use.
An item has its advantages, naturally has its disadvantages, infrared detector is greatly affected by the environment, such as the amount of radiation around the size of the surrounding wind, size, temperature, and even said that the radiation of other objects will affect the accuracy of its detection, but we just as a tool for detecting the temperature of the body, there will not be too much error, the temperature of the body, the body temperature, the temperature of the body temperature, the temperature of the body temperature, the temperature of the body temperature, the temperature of the body temperature, the temperature of the body temperature, the temperature of the body temperature, the temperature of the body temperature. Generally speaking, in 0.2 degrees to 0.3 degrees or so, so the measured data is still quite accurate, avoiding the frequent use of thermometers to measure body temperature, both to delay their own time and affect their own trip.
Infrared detector to some extent is also an optical application, because it is based on the object reflected back to the proportion of how much to determine the temperature, but this is a fine-tuning process, is the need for this machine factory data regulation, are tested in advance before the market, Others, such as laser ranging laser, engraving is the optical aspects of the laser, the laser, the laser, the engraving is the optical aspects of the laser, the laser, the engraving is the optical aspects of the laser.
Laser Ranging, Laser Engraving, Optical Applications, Practical Applications in this area is still quite a lot, because it is more secure and there is no great cost.
