Note.
In the development process of Standard Ratio thermometer, inhibiting Source size effect is the part for needing to pay close attention to.Work as survey
When measuring or comparing that two sizes are different but the identical black matrix of temperature, it is often not identical to detect the monochromatic radiation brightness received,
Here it is Source size effects.The reason of causing Source size effect is that the radiation measured other than target passes through different optics, mechanical member
Folding between part/reflect to form stray light, is received by a detector into optical path.
In order to inhibit Source size effect, it is necessary to limit stray light and enter detector.The main method taken at present be
The veiling glare door screen that disappears is added in thermometric optical path before detector.But this method is limited to light channel structure, be typically only capable to be added individually disappear it is miscellaneous
Diaphragm, while each optical element in thermometric optical path is independent of one another, is not packaged together with detector, so that the miscellaneous effect that disappears has
Limit.
Summary of the invention
Disappear the problem that miscellaneous method inhibits Source size effect effect limited the purpose of the present invention is to solve traditional optical, mentions
A kind of Source size effect based on radiation thermometer inhibits device out.
The purpose of the present invention is what is be achieved through the following technical solutions.

Disappear veiling glare door screen, to inhibit to Source size effect.
A kind of Source size effect inhibition device based on radiation thermometer, internal optical path trend are as follows:
Diaphragm reflecting mirror is crossed by the temperature measuring optical Reuter of radiation thermometer, through optical path encapsulation cylinder collimation, converges to optical path encapsulation cylinder
On interior detector；The veiling glare door screen that disappears being mounted in optical path encapsulation cylinder masks the stray light other than main optical path, while will be spuious
Light is reflected on the perforation screw thread in optical path encapsulation cylinder, and spurious rays become irregular diffusing reflection in screw thread, and then inhibit
Source size effect.
Beneficial effect
Compared with traditional radiation thermometer thermometric optical path installing component, Source size effect of the invention inhibits device by light
Late reflecting mirror and collimation convergence optical path overall package later avoid in radiation thermometer other elements from generating in confined space
Stray light enter detector.Compared with the single veiling glare door screen installing component that disappears, Source size effect of the present invention inhibits device can be with
The veiling glare door screen that disappears of one or more different-diameters is installed in different location, it is more preferable to the inhibitory effect of Source size effect.
