CCD混频现象的实验研究
Experimental Study of CCD Aliasing Phenomenon
【摘要】 利用自制的CCD调制传递函数测量系统,记录了线阵CCD在对频率可连续变化的正弦光栅图样采样过程中,发生的混频现象。并对发生混频的区域进行了测量,测量结果与理论计算结果吻合。
【Abstract】 We have recorded the aliasing phenomenon using the measurement system of modulation transfer function of CCD equipped by ourselves,which occurs during measuring of the model TCD linear CCD with the frequencies variable sine grating pattern.We have also calculated the region of aliasing.The measured results agree with the theoretical analysis.
