摘要
分析说明了积分球存在一次反射短时平均等照度性质 ,提出了积分球的几个概念 :平均反射程λ、平均反射时间 μ、平均反射率 ρ、平均出射程 η、平均出射时间τ(等于积分球的时间常数 )。用分析方法推导了积分球时间常数的一般表达式、积分球对δ函数形式的功率波形的变换表达式、积分球对任意光功率波形的变换表达式及其反变换表达式。
The single reflection short-time-average uniform irradiance character of the integrating sphere is introduced. Several concepts such as average reflection distance λ, average reflection time μ, average reflectance ρ, average emission distance η, average emission time τ (right be the time constant of an integrating sphere) are presented. The equation of time constant of an integrating sphere is derived. The equations of transform of light power waveform with δ function and arbitrary functions and the equation of reverse transform are derived too.
