| Abstract: | In this paper, the mechanical construction, thermal regulator design and temperature measurement system of a local area were
set up for large-scale linear measurement. Numerical analysis based on temperature correlated characteristic is discussed
to obtain optimal observation points for the measurements. The horizontal temperature distribution of the measured area is
compared with the measurement of the variation of temperature at 15°C and 20°C over time, and characteristic of dynamic response
is also discussed. In addition, the long-time stability of measured temperature is analyzed by means of using the standard
deviation. It characterizes the temperature distribution performance of a large area and how it may impact the measurement
of a large-scale object. |
