为了研究更新和刷新率对动态书法CRT显示器，特别是用于飞行模拟器视觉显示器的动态书法CRT显示器的影响，进行了一项实验。在CRT上产生一条移动的水平线，并以不同的速度观察。每次更新一次和两次刷新进行观察。从这些观察中收集的数据被呈现在刷新更新率作为显示速度的函数的图上。通过使用这些曲线图，可以找到发生图像劣化的显示速度。这些速度与实际模拟的飞机角速度和线速度有关。结果表明，在非常低的模拟飞机角速度和线速度下，以30 Hz更新并以60 Hz刷新的视觉显示会退化。通过增加视觉显示器的更新速率，可以显著地增加发生退化的这些速度。通过每次摄取刷新显示两次，仅可能进行微小的改进。为了显示快速变化的飞行场景而不降级，显示更新速率必须远远超过60 Hz，通常为几百Hz。
An experiment was performed to study the effects of update and refresh rates on dynamic calligraphic CRT displays, particularly those used for visual displays in flight simulators. A moving horizontal line was generated on a CRT and observed at various velocities. Observations were made with both one and two refreshes per update. The data gathered from these observations are presented on plots of refresh-update rate as a function of display velocity. The display velocity where picture degradation occurs can be found by using these plots. These velocities are related to actual simulated aircraft angular and linear velocities. Results show that a visual display updated at 30 Hz and refreshed at 60 Hz degrades at very low simulated aircraft angular and linear velocities. These velocities at which degradation occurs can be significantly increased by increasing the update rate of the visual display. Only minor improvements are possible by refreshing the display twice for each uptake. To display rapidly changing flight scenery without degradation, the display update rate must be far in excess of 60 Hz, typically several hundred Hz.
