The radiometric calibration technology for ultraviolet intensifier CCD (UV-ICCD) detector is a new researching direction. It is necessary to study on the technology of UV-ICCD calibration to sure the test results’ accuracy and reliability. The purpose of the radiometric calibration for UV-ICCD is to build the relationship between the input irradiance and the digital output. The theory of radiometric calibration was derived. The radiometric calibration of the UV-ICCD was implemented in the laboratory. The calibration method is based on spectral irradiance standard deuterium lamp. Uncertainty of the deuterium lamp calibrated by NIST is 5%. The response of the UV-ICCD was tested under fixed MCP gain and fixed integration time. The relationship of the response with the MCP gain was studied. The preliminary analysis of calibration data shows that response of the UV-ICCD is linear and the MCP gain is in positive proportion to the average grey value of image. At last the uncertainty which influences the results of calibration was analyzed. The analysis of the uncertainty shows that the measurement accuracy is 7.94% and meets the requirement.
