FREQUENCY RESPONSE TEST CHART YE152/TE152
The test chart shows line rasters over the whole image area ranging from 1 to 8 MHz.
Below the line rasters (in the black surrounding area) there are line markings with the respective MHz figures. The bars on the left and right sides of the picture (2 black and white cycles on each side) have a frequency of 0.5 MHz and serve as reference value. The width of the line rasters decreases step by step, however not within the black and white cycles. Between two MHz cycles white whole numbers the bar width decreases in 20 regular steps.
With help of an oscilloscope the frequency response of a camera can be checked. For this purpose it may be useful to take into the camera picture the MHz marks outside the actual test chart picture.
