CINE RESOLUTION TEST CHART

REFLECTANCE

The test chart is used for evaluating the resolving power of a cine camera.

For this purpose the chart is set at a distance of the x-fold of the focal length to the centre

of the lens. The x-fold of the focal length corresponds to the reduction scale. The following

diagram shows the reduction scale 25, 50, 100, 200, 400 and 800. The resolution is indicated

in line pairs/mm, actually for each of the fields marked C to K.

			line pairs / mm with reduction scale
field	25	50		100	200	400	800
C	59.1	118.2		236.4	472.8	945.6	1891.2
D	41.8	83.6		167.2	334.4	668.8	1337.6
E	29.6	59.1		118.2	236.4	472.8	045.6
F	20.9	41.8		83.6	167.2	334.4	668.8
G	14.8	29.6		59.1	118.2	236.4	472.8
H	10.5	20.9		41.8	83.6	167.2	334.4
I	7.4	14.8		29.6	59.1	118.2	236.4
J	5.2	10.5		20.9	41.8	83.6	167.2
