产品详细介绍
1. Resolution property of imaging device is measured by taking the bright and dark fringes as an object.
Amplitude modulation factor depends on the direction of slope of fringe and luminous energy. Also γ characteristic of imaging device affects it a lot.
This chart is well designed for measuring, evaluating and adjusting a signal processing circuit and an imaging device, with understanding the phenomenon stated above
2. (1)Black and white patterns in the vertical direction
There are 350TV because chrominance carrier of a normal single-lumen color camera is 3.5 to 4.5MHz.
(2)Black and white patterns slope to the left and right.
Inclined angle to left and right is ±20° and there are 350TV.
