外部导入激光的积分球辐射源研制和特性研究

为了满足近年来迅速发展的光谱辐射遥感器的定标需求，我们研制了一种新型的外部导入激光的积分球辐射源。这种积分球辐射源不仅完全满足辐亮度响应度定标对定标光源的要求，而且可以对高光谱、超光谱仪器的光谱辐射响应度进行精细扫描。我们首先导入单波长激光对积分球辐射源的基本辐射特性进行了研究，包括辐亮度非稳定性、平面非均匀性和角度非均匀性。特性测试结果表明，这种新型的利用激光的积分球辐射源的各种特性与传统的灯照明积分球辐射源在同一水平内。由于其具有光谱辐通量高、单色性好、波长准确性高、可宽波段调谐等优点，有着广泛的应用前景

The Development and Characteristics Research of the Laser Illuminated Integrating Sphere

For calibration of the recent developded spectral radiation remote sensor, we have built a newly integrating sphere source which introduced laser outside. This integrating sphere source not only meet the demand of calibration souce for radiance responsivity calibration, but also can scan the spectral responsivity accurately. We have introduced singel-wavelength laser to research the basic radiation characteristics of the integrating sphere source, which include radiance instability, plane uniformity and Lambertian. The result show that this newly integrating sphere source is highly stable and uniform.
