| Abstract: | Light-emitting diode(LED) is a compound semiconductor device. In optical radiometry and calibration， LED has good performance of high luminance， energy-cost savings and long life. It is new reference source of radiometry，photometry and colorimetry. Because of its small bulk and low power， LED is regarded as complementarity of lamp and used in calibration of remote sensing. Application of LED in optical radiometry and research progress in the field are introduced， and a bright future has been brought forward. |
