Effect of changing the MCP´s bias angle on resolution of image intensifier

This paper studies the impact of MCP´s bias angle on the resolution of image intensifier. To analyze this we obtain the mathematical expression of voltage at every point by resolving the Laplace equation with the finite difference method. Then, we substitute values to the mathematical expression and calculate the voltage in discrete points until the error less than a certain value with the over-relaxation method. Secondly, with the voltage distribution, we compute the distribution of equipotential lines with the trajectory tracing method and calculate the electron trajectories by Hechtel method. Finally, the line spread function is calculated from the placement distribution on the phosphor of the electron trajectories. Then the MTF at the different spatial frequency on the phosphor is gained by the line spread function for Fourier transform.
