摘　　要：根据ICCD、BCCD和EBCCD的结构特点,分析了三种器件的MTF特性,并在相同目标条件下计算比较了它们的SNR。研究表明,在中等光强下BCCD的性能优于ICCD,而在极弱的光强下,EBCCD能取代ICCD。Based on the structural performances of ICCD,BCCD and EBCCD,their MTF performances is analysed and their SNR is calculated. It is shown that under moderately low light conditions,the performance of BCCD is better than that of ICCD.Moreover,under extreme low light conditions,ICCD can be replaced by EBCCD.
