System design of dot temperature measurement instrument

Aiming to solve the problem that measurement of the infrared instrument is not accuracy enough and is vulnerable to be affected by environment,distance,and radiation,a kind of new instrument of dot temperature measurement was designed,which was based on optical and thermal theory,using the principle of telescope.The general lens were instead by GRIN lens,then the optical fiber receives light waves in the image plane and the signal was transmitted to signal processing unit,really reaching the goal of dot temperature measurement.The principles and methods to design the software and hardware about the system were provided.The result indicates that the requirements of non-contact industrial temperature measurement are completely acquired through the precise calibration and commissioning.
