Abstract: A power supply for supplying a power to a heating mechanism used for heating a measurement target that emits a measurement signal includes an input device configured to output an input signal that reflects a control signal in a differentiable periodic waveform having a frequency of 1 kHz or less. The power supply includes a switching amplifier configured to amplify the input signal from the input device and output the amplified signal.

Abstract: A temperature calibration system includes: an inspection apparatus to adjust temperature of an inspection target in a placement part and inspect the inspection target; and a surface thermometer, and is configured to calibrate temperature sensors in the placement part. The inspection apparatus includes: a carriage to move the placement part in X-, Y-, and Z-axis directions; and a controller to perform a calibration process to measurement values of the temperature sensors. The surface thermometer is configured to contact a placement surface of the placement part and detect a surface temperature of the placement surface. The controller is configured to: control the carriage to contact the surface thermometer with a detection position of the placement surface of the placement part; detect the surface temperature of the detection position by the surface thermometer; and calibrate the measurement value of the temperature sensor corresponding to the detection position based on the surface temperature.
