Because of the calibration requirements of large-area infrared remote-sensing equipment, a large-area blackbody radiation source with the area of 1.05 m × 1.05 m is developed at the National Institute of Metrology (NIM), China. The temperature range of the blackbody is from room temperature to 573 K...
