摘　　要：为了解决国内外能见度参数量值无法绝对溯源的问题,利用透射式能见度仪的工作原理、结构特点以及环境条件,提出了溯源至几何量的量值复现方法,设计了1套高透射比量具作为主标准器,实现了对透射式能见度仪的校准,促进了能见度参数量值溯源体系的发展。主标准器遮光体采用精密机械加工工艺,遵循几何量参数测量的绝对溯源法,可大幅减小透射比量值的测量不确定度;主标准器滤光片根据几何量测量和光学透射比参数测量相结合的溯源链,解决了现有技术中高透射比无法复现和准确测量的问题。此外,使用锥形遮光体,可避免引入除旋转因素外的其他不确定度来源,大幅提升了能见度仪分辨率的校准能力。In order to solve the problem that the quantity value of visibility parameters at home and abroad cannot be absolutely traceable,the quantity value reclaiming method tracing to the geometry amount was proposed by using working principle,structural characteristics,and environmental conditions.A high transmission visibility instrument as the main standard device was designed to calibrate the transmission visibility meter,which promoted the development of visibility value to trace the origin system.The main standard device used precision processing technique,which followed the absolute traceability method of geometric parameter measurement,and could greatly reduce the measurement uncertainty of the transmission ratio.The traceability chain combined with measurement of geometry and optical transmittance parameter solved the problem that could not reproduce and accurately measure the high transmission ratio in existing technologies.In addition,the use of cone occulter could avoid the introduction of other sources of uncertainty except rotating factors,which greatly improved the calibration capability of the visibility meter resolution.
