光照射到CCD摄象器件的光敏面上将产生电子——空穴对,其中的少数载流子被时钟脉冲产生的势阱取样,然后聚集起来形成信号电荷包,进而在时钟脉冲驱动下由移位寄存器转移到输出端而取出。本文讨论信号电荷在CCD中的转移过程。在三相CCD中,信号电荷包存储在其中 Light impinging on the photosensitive surface of a CCD camera produces electron-hole pairs in which minority carriers are sampled by the potential wells generated by the clock pulses and then gathered to form signal charge packets, which in turn are driven by the clock pulses The shift register is shifted to the output and taken out. This article discusses the signal charge in the CCD transfer process. In the three-phase CCD, the signal charge packet is stored therein
