| 摘要 | In order to break through the bottleneck of traditional CCD camera in suppressing noise, this paper designs a new system of digital domain correlation double sampling. The CCD video signal is digitized by a high-speed, high-resolution A/D converter at a sampling frequency much higher than the readout rate, and then an optimal digital signal processing algorithm is designed for the characteristics of the CCD signal readout noise to suppress noise. Experiments show that the system can suppress the readout noise at 8.1 e- at 500K read rate, which can reduce the output noise of CCD more effectively. © 2019 SPIE. |
