The customized Fiber Optic Pyrometer is a pyrometer that converts the state of the measured object into a measurable optical signal. The working principle of the customized Fiber Optic Pyrometer is to send the light beam incident from the light source to the modulator through the optical fiber, and interact with the external measured parameters in the modulator to make the optical properties of light such as light intensity, wavelength, frequency, phase, and polarization. The state and other changes become modulated optical signal, which is sent to the optoelectronic device through the optical fiber, and the measured parameter is obtained after the demodulator. In the whole process, the light beam is introduced through the optical fiber, and then emitted after passing through the modulator. The function of the optical fiber is first to transmit the light beam, and secondly to act as a light modulator. The customized Fiber Optic Pyrometer is developing in the direction of flexibility, accuracy, compliance, compactness and intelligence.

In this process, the customized Fiber Optic Pyrometer, a new member of the pyrometer family, is very popular. Optical fiber has many excellent properties, such as: anti-electromagnetic and atomic radiation interference performance, small diameter, soft, light-weight mechanical properties; insulation, non-inductive electrical properties, water resistance, high temperature resistance, corrosion resistance, chemical properties, etc. , It can play the role of human ears in areas that are out of reach (such as high temperature areas) or areas that are harmful to humans (such as nuclear radiation areas), and it can also transcend human physiological boundaries and accept human senses. Information from the outside world that you can't feel.

The customized Fiber Optic Pyrometer has the advantages of wide transmission frequency bandwidth, large communication capacity, low loss, immunity to electromagnetic interference, small diameter of the optical cable, light weight, and abundant source of original data. Therefore, it is becoming a new transmission medium. When light is transmitted in an optical fiber, loss occurs. This loss is mainly composed of the transmission loss of the optical fiber itself and the splicing loss at the optical fiber joint.
