| 摘 要： | 本文从Lucovsky方程入手,根据rc传输线模型和理想脉冲响应函数,提出PSD线性时不变系统(LTI)的模型近似,并基于该模型得出一般模式点光源下的PSD的响应函数.光强随时间变化的点光源可以均匀分割成一系列时域脉冲信号,并近似认为是方波脉冲信号,在线性时不变系统情况下,该光源的电流响应近似等于这些方波脉冲信号的线性...

| Abstract: | A PSD is modeled as an approximate Linear Time Invariant(LTI) system based on the rc transmission line model and the impulse response obtained from Lucovsky equation.Based on the model,the PSD general response is derived.In our processing,a time-varying light signal is divided into many sections in time domain.Each section is regarded as a square-wave pulse.And the response is approximated to be a linear superposition of those pulse responses.Results show that the response is the summation of product of two... |
