一种亮度可调积分球光源及其应用技术研究

Research on brightness adjustable integral sphere light source technology and its application

  • 摘要: 目前辐亮度计的光谱辐射响应函数采用辐照度标准灯和漫反射白板的方法进行校准,无法实现大动态范围内的线性校准。提出了一种高精度、亮度可调积分球光源,利用固定光阑和可变光阑控制输出辐射亮度,动态范围达到4个数量级;通过对遮光筒式辐亮度计的光谱响应函数进行测试,实验结果表明:遮光筒式辐亮度计的光谱响应函数具有很好的线性特性,且重复性高,一次项系数的标准差为2.78E-17。

     

    Abstract: At present, the spectral radiation response function of the radiometer is calibrated by the irradiance standard lamp and diffuse reflector whiteboard, which cannot achieve linear calibration in a large dynamic range. A high-precision integral sphere light source with adjustable brightness was proposed. The output radiance was controlled by fixed and variable apertures, and the dynamic range reached 4 orders of magnitude. In addition,the spectral response function of the barrel-type radiometer was tested The experimental results show that the spectral response Function of barrel radiometer has good linear characteristics, high repeatability and the standard deviation of one-term coefficient is 2.78E-17.
