The Methodological Research On Partial Vision Field Target Temperature Measurement

Based on the due discussion about the development and the application of the infrared radiation thermometry in our country and abroad, the paper give a due discussion on the distance of measure temperature and the vision field of thermometric and all sorts of influence factor. Through analysis the experimental results, we fitting out a functional relation expression.The development of radiation temperature measurement has been reviewed and the problems were analyzed from technique degree. And it introduced the main objects and study situation.Based on the theory of infrared radiation and the principles of temperature measurement, contacting with the working principle of thermal imager, the author analysis its main performance parameters and the precautions.Program the computer, calculate the ration of the measured target on the whole field of view, and analysis the result.Analysis the relation of target temperature and measured distance and vision field of target through the experiment.It is the summary to the whole paper at the last part..
