中文摘要:
      为了实现校准能见度仪用标准散射体的快速高精度定标,依据标准散射体校准前向散射式能见度仪的校准原理,提出了一种新型的校准能见度仪用标准散射体定标系统,重点研究了该系统的装调技术。根据定标系统的组成与工作原理,建立了定标系统装调光学模型,并提出由抛物面反射镜与全景成像能量检测系统相对位置装调以及抛物面反射镜与低反射率球形屏幕系统相对位置装调组成的定标系统装调方案。建立校准能见度仪用标准散射体定标系统极限误差计算模型,在入射光线角度为45°的情况下,计算出装调过程中抛物面反射镜与低反射率球形屏幕系统平移误差与倾斜误差的极限装调误差分别为3.18°和0.847°,抛物面反射镜与全景成像能量检测系统平移误差与倾斜误差的极限装调误差的极限装调误差均为2.14 pixel。实验证明装调后的校准能见度仪用标准散射体定标系统的最大角度检测误差为0.795°,满足定标系统的角分辨率是1°的使用要求。
英文摘要:
      In order to realize rapid and high precision calibration of the standard scattering plate for visibility meter calibration, based on the calibration principle of standard scatter plate used in calibrating forward scattering visibility meter, we proposed a new type of calibration system for standard scatter plate used in calibrating forward scattering visibility meter. The main research focus was the alignment technology for the calibration system. According to composition and working principle of the calibration system, we established the alignment optical model. We also proposed the alignment scheme consist of the alignment of relative location between parabolic reflection mirror and panoramic imaging energy detection system and relative location between parabolic reflection mirror and low reflectivity spherical screen system. We established extremity error calculation model. In the situation of 45°pitching angle of incident light, we calculated the maximum alignment error of translation error and tilt error between parabolic reflection mirror and low reflectivity spherical screen system are 3.18°and 0.847° respectively, and the maximum alignment error of translation error and tilt error between parabolic reflection mirror and panoramic imaging energy detection system are both 2.14 pixels. The experimental results proved that the maximum angle detection error of the alignment standard scatter plate calibration system used in calibrating forward scattering visibility meter is 0.795°, which is less than 1° and satisfied the requirements of angle detection error of the calibration system.
