以测试结果为例

讨论和描述该矩阵的应用和结果。实验结果表明:该CCD近似成线性响应

通过矩阵函数可以计算出CCD非均匀性为3.1%

暗噪声为3.84。此方法实用

满足对大格式CCD直观表述的要求。

Abstract

To describe the parameters of a big format Charge Coupled Device (CCD) by a function with definit physical meaning and to evaluate its radiation response performance directly

a concept of "radiation response function matrix" was proposed to describe the radiation response parameters of each pixel of the CCD. Firstly

by analyzing the physical concept of each element

some parameters such as absolute radiate response

nonlinearity

dark noise

Signal-to-Noise Ratio (SNR) and the non-uniformity of each pixel of the CCD were characterized by the matrix. Then

response characteristic coefficient of each pixel was obtained using the model of multiple regression analysis by a test on the area CCD KAI-16000. Finally

by taking the result for an example

application of this matrix was discussed. Experimental results show that the response of this CCD is linear

and its non-uniformity is 3.1%

dark noise is 3.84. These results demonstrate that the method is feasible and practical

and it can satisfy the requirement of the description of a big format CCD.
