Abstract

The application provides an array programmable temperature field calibration device and method, belonging to the technical field of temperature measurement and calibration. The device comprises a system control unit, a plurality of temperature control units, a bidirectional temperature control module and a composite heat insulation structure. The system control unit is used to generate control instructions corresponding to a target two-dimensional temperature distribution pattern, and a graphical interface is provided for users to set the pattern. The plurality of temperature control units are arranged in an array to form a radiation surface, and each temperature control unit receives independent control instructions. The bidirectional temperature control module is integrated in each temperature control unit, and is used to independently adjust the temperature of the radiation surface of the unit according to the received control instructions. The composite heat insulation structure is arranged between adjacent temperature control units, and is used to suppress the thermal cross talk between the units. The application can flexibly and efficiently generate a high-precision programmable two-dimensional temperature field, which is used for comprehensive calibration of non-contact temperature sensors.
