AUTOMATED CALIBRATION BENCH FOR CALIBRATION OF RADIATION THERMOMETERS

In order to improve and optimize the procedure for calibration of radiation thermometers, an automated calibration bench was developed. Manual calibration with the help of special stands is time consuming and less reliable compared to automated calibration. The developed calibration bench has 5 degree of freedom (DOF) (3 translation joints and 2 rotation joints). For each axis we have used motorized movement control by means of a stepper motor. Stepper motors control circuit has built-in microcontroller, which controls the speed and direction of rotation of the stepper motors and communicates with the PC. The user interface is implemented as a virtual instrument in LabVIEW programming environment.
