摘要: 本文介绍研制的显象管调制传递函数测量仪器,用客观的方法测量各种工作条件及屏面不同位置的调制传递函数,精度为±3%。并可以执行国家标准来测试显象管的分辨能力.提出了压缩法测量分辨率时避免假分辨现象的方法.

Abstract: A new instrument for modulation transfer function (MTF) measurement of TV picture tube has been designed. It can measure MTF of different areas on screens under different conditions with precision up to +3%, and the resolution is measured in accordance with the standards issued by the National Bureau of Standards, the People's Republio of China. A way to avoid false resolution phenomenon when using a compression method is given in the paper.
