1.    Sometimes slope of stripes causes a difference in resolving power of imaging device, especially pick up tube though the same number of TVs in a taken image. This is a phenomenon caused by an elliptic imaging aperture.

In Radial Resolution Chart, wedge-shaped fringes are circularly arranged alternately with white and black. The circles drawn by the line width 1/1500h are located in 200TV, 400TV and 800TV.(h is a height of a chart)
