The noise of a digital charge coupled device (CCD) detector increases with the readout speed, causing problems in a number of important applications, such as x-ray fluoroscopy and micro-CT. In this paper, we present an approach for the design of a dual-CCD configuration to improve the average signal-to-noise ratio, and hence provide an inexpensive solution within the constraint of the current technology.
数字电荷耦合器件(CCD)探测器的噪声会随着读出速度的增加而增大,这在许多重要应用中引发了问题,比如X光透视和微型计算机断层扫描(micro-CT)。在本文中,我们提出了一种设计双CCD配置的方法,以提高平均信噪比,从而在现有技术的限制范围内提供一种低成本的解决方案。
