Thermal imaging technology under the pandemic COVID-19

Feb. 22, 2021

The epidemic caused by the coronavirus has spread all over the world from 2020. Its main transmission route is through respiratory droplets and contact transmission. Various countries have proposed preventive measures for the transmission of the virus, keeping distance and wearing masks, and always pay attention to whether there is fever. Infrared thermal imaging  technology effectively manages to rapid and accurate measure body temperature.

According to different places of needs, the design of infrared products is also different, mainly using infrared technology and AI technology. First, the thermal imager detects and records the temperature of the man. The camera records the facial features of the man. The data of the man is transferred to the host. The host judges whether the man could enter according to the former data. If the body temperature is too high, the man cannot enter; if the man does not have permission, the man also cannot enter.

Infrared thermal imaging cameras use infrared detectors, optical objective lenses and an optomechanical scanning system. The scanning system receives the infrared radiation energy of the measured target and reflect it on the photosensitive element of the infrared detector. Between the optical system and the infrared detector, the optomechanical scanning system scans the infrared thermal image of the measured object and focuses on the detector. The detector converts the infrared radiation into an electrical signal, which is amplified and converted into an infrared thermal image displayed on the screen.

The human body temperature detection with thermal imaging system contains optical lenses, which is non-contact, fast, convenient, and intuitive. It overcomes the shortcomings of traditional clinical thermometers, such as forehead thermometers, spot thermometers and ear thermometers. They are only for individual measurement, which is time-consuming and easy to cross infection. In addition to detecting body temperature, the system also detects whether the man is wearing a mask. Besides, the system also records, when the temperature is measured and when the man arrives at the company. So the body temperature can be used with turnstiles to control entry and exit of people. Infrared temperature measurement products effectively control the spread of the epidemic. They are suitable for rapid measuring body temperature. They could be used in government agencies, public transportation, hospitals, shopping malls, and companies, where there is a large flow of people.

CLZ Precision Optics Co., Ltd. produces optical lenses for infrared thermal imaging cameras and other cameras, including biconvex lenses, plano-convex lenses and other optical lenses. Our company will not only produce custom optical lenses, but also optical domes, optical windows, optical mirrors and optical prisms according to customer's requirements.
