针对光谱分析实验中线阵CCD灵敏度较低,提出了一种Binning 技术可将几个相邻的像素合并一个像素,提高线阵CCD的像素响应度、信噪比和CCD的帧速。研究包括光谱色散成像、CCD、光谱数据分析。研究表明,通过改变CCD的驱动时序,对光谱族中的敏感波段实现合并(Binning),可获得更高的灵敏度和信躁比。对相邻像素合并造成的影响进行了讨论。

A method combining several pixels into a pixel using Binning technology is proposed,considering that delicacy of linear CCD is lower in spectral analysis. Thereby several performances of linear CCD,such as responsibility,sing-noise ratio and frame speed are enhanced. The researches include discussing the sign output structure of a CCD,and capturing the spectrum family,and analyzing data of sample. They indicate that combining sensitivity sub-family of spectrum together (Binning) through changing drive sequence of CCD,can get higher sensitivity and signal-noise-ratio (SNR). The influence of Binning on near pixels is discussed.
