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 integral sphere has several properties such as average reflection range λ, average reflection time μ, average reflection rate ρ, average emission range η, average emission time τ (equal to Integral sphere time constant). The general expression of the time constant of the integrating sphere is deduced by the analytical method. The transform expression of the power waveform of the integrating sphere to the delta function form, the transform expression of the integrating sphere to any optical power waveform and the inverse transform expression are derived.
