Description
Technical Field
The utility model belongs to the technical field of the installing support, concretely relates to portable infrared radiation thermometer.
Background
Infrared thermometry has been developed to scan and measure the temperature of a surface with thermal changes, determine the temperature distribution image, and quickly detect the hidden temperature difference, which is known as thermal infrared imager. In the future, the infrared thermal imaging technology is successively applied to airplanes, tanks, warships and other weapons in western countries, and is used as a thermal aiming system for detecting targets, so that the target searching and targeting capabilities are greatly improved. The Fuluke infrared thermometer is in the leading position in civil technology. However, how to make the infrared temperature measurement technique widely used still remains an application subject worth being studied.
The infrared thermometer consists of an optical system, a photoelectric detector, a signal amplifier, a signal processing part, a display output part and the like. The optical system converges the infrared radiant energy of the target in the field of view, and the size of the field of view is determined by the optical parts of the thermometer and the position of the optical parts. The infrared energy is focused on the photodetector and converted into a corresponding electrical signal. The signal is converted into the temperature value of the target to be measured after passing through an amplifier and a signal processing circuit and being corrected according to an algorithm in the instrument and the target emissivity.
In nature, all objects with a temperature higher than absolute zero continuously emit infrared radiation energy to the surrounding space. The magnitude of the infrared radiation energy of an object and its distribution by wavelength are very closely related to its surface temperature. Therefore, by measuring the infrared energy radiated by the object itself, the surface temperature can be accurately measured, which is the objective basis on which infrared radiation temperature measurement is based.
The principle of infrared thermometer is that a black body is an ideal radiator, which absorbs radiation energy of all wavelengths, has no reflection and transmission of energy, and has an emissivity of 1 on the surface. However, the actual objects existing in nature are almost not black bodies, and in order to clarify and obtain the infrared radiation distribution rule, a suitable model must be selected in theoretical research, which is a quantized oscillator model of body cavity radiation proposed by planck, so that the planck black body radiation law, namely the black body spectral radiance expressed by wavelength, is a starting point of all infrared radiation theories, and is called as the black body radiation law. The amount of radiation of all real objects depends on factors such as the kind of material constituting the object, the preparation method, the thermal process, and the surface state and environmental conditions, in addition to the wavelength of the radiation and the temperature of the object. Therefore, in order to apply the blackbody radiation law to all real objects, a proportionality coefficient, i.e., emissivity, must be introduced, which is related to the material properties and the surface state. This coefficient represents the proximity of the thermal radiation of a real object to the black body radiation, with a value between zero and a value less than 1. According to the radiation law, the infrared radiation characteristic of any object is known as long as the emissivity of the material is known. The main factors affecting emissivity are: material type, surface roughness, physical and chemical structure, material thickness and the like.
Current infrared radiation thermoscope includes the portion of holding and temperature measurement portion, and the two integral type is connected, and the convex temperature measurement portion is great with the space that the portion of holding occupied, and is not portable.
