Analysis on the Non-Uniformity of ICCD Caused by Fiber Optic Taper Coupling

In order to improve the uniformity of fiber optically coupled intensified CCD(ICCD),its mechanism of formafion is analyzed.A graphic method is adopted to demonstrate how the non-uniformity is caused.The microstructures of CCD pixels, fiber optic taper and intensifier fiber output panel are analyzed.The process of formation of non-uniformity is illustrated by the composition of real images and the main factors contributing to non-uniformity are described in detail.Severity of non-uniformity is revealed,and its solutions proposed so as to reduce the non-uniformity of ICCD by reducing the fiber diameter of fiber optic taper.
