摘要
本文介绍了漫透射视觉密度基准的测量装置 ,详细论述了该基准装置改造时光路调试中应用的数值计算方法。通过计算 ,调整了测量光路中各个透镜的几何位置 ,使计算前后漫透射视觉密度基准装置测量的最大入射光通量有了 2 5%提高 ,因此降低对整个基准测量装置中溴钨灯光强、测量仪表灵敏度的要求 ,并可以使测量范围适当加宽。
A measuring instrument about diffuse visual transmission density is introduced, and a numerical calculating method is discussed, which is applied in the advanced research. Recording the result of calculation, the geometric position of lens in light path is acquired, and the maximal incident luminous flux increase 25 percent. It can reduce the light intensity of halogen lamp and sensitivity of measured instrument, and measured range can be widened.
