Since the current produced by light activated triode is larger , it is possible to use common microammeter to measure the photocurrent , making the experiment easier 由于光敏三極管的光電流較大,測試光電流時(shí),可用普通的電流表(微安表)進(jìn)行測量,使實(shí)驗(yàn)變得簡單可行。
This paper introduces a new method to measure the intensity distribution of single seam diffraction by replacing the silicon photocell and light activated diode with light activated triode 摘要利用光敏三極管代替硅光電池和光敏二極管來測試單縫和雙縫衍射的光強(qiáng)分布。
The influence of the detecting array on the spectrum signal is studied . a solution is put forward to correct the displacement error caused by width of the light activated element , when the sampling theorem is satisfied 提出了在滿足采樣定理的前提下,采用頻域反卷積的方法來消除由像元寬度對光譜峰值定位造成的亞像元誤差。
