| 摘 要： | 从积分球非中性的角度出发,研究了光(辐射)经过积分球后的光谱性质变化.根据积分球理论公式,推导了积分球光谱透过率的非中性与内壁涂层光谱反射比非中性的关系,证明积分球非中性通常大于内壁涂层非中性;且内壁涂层非中性一定时,涂层反射比越高,积分球非中性越大.然后分别以A光源和氙灯作为入射光源,测量了硫酸钡和聚四氟乙烯两种典型...

| Abstract: | Changes in spectral properties of output light are analyzed from the angle of integrating sphere non-neutrality.Based on integrating-sphere theory,the relationship between non-neutrality of integrating-sphere spectral transmittance and that of spectral reflectance of inner coating is derived.It shows that non-neutrality of integrating spheres is usually greater than that of inner coatings,and integrating sphere non-neutrality increases with the rise of coating reflectance when coating non-neutrality remains... |
