AbolishedTest charts of reflection for television--High-frequency test chart
反射式电视测试图 高频特性测试图
Application Summary AI generated
This standard specifies a high-frequency test chart used to evaluate the resolution and high-frequency response of reflection-type television systems. It is applied in the manufacturing and quality testing of television cameras, monitors, and imaging devices, particularly for assessing performance in broadcast, surveillance, and industrial imaging contexts. The chart enables engineers to measure signal degradation and sharpness under controlled lighting conditions.
