1951 USAF Resolution Test Pattern

Step one of the resolution test is done by scanning the optical target

Step one: Scan optical resolution target, notice how the target repeats itself

Step 2: You read the chart by observing line pair separation or lack there of depending
depending on where this lack of separation occurs references the element and
group chart.

Groups

Elements	2	3	4	5	6	7
1	4.00	8.00	16.0	32.0	64.0	128
2	4.49	8.98	17.9	35.9	71.8	143
3	5.04	10.2	20.1	40.3	80.6	161
4	5.66	11.3	22.6	45.3	90.5	181
5	6.33	12.7	25.4	50.8	101	203
6	7.13	14.3	28.5	57.0	114	288

Step3: Depending on what the results are in this case element 4 groups 6 note results Text Box: Dots Per Inch = [ (Line Pairs / mm ) x 2 ] x 25.4 mm / Inch

Text Box: Visible Line Pairs / mm are the equivalent of True
Optical Dots Per Inch

Text Box: GROUP 6 ELEMENT 4 has 90.5 line pairs per mm
[( 90.5 x 2 )} 25.4 = 4597.4 visible dots per inch

Text Box: The Scanner Optical Resolution is 4597.4 DPI

Step4: From the information gathered from the chart you can now find the
optical performance of the scanner.

Density Test

Kodak Q59 ST-34
Scanner Calibration Target

Step1:

Text Box: ISO Status A Density .1 to 3.4 Simply
Scan the Target and Check the Scan
Result for the Range of Changing Intensities

Step 2: After opening the scanned Kodak Q59 ST-34 in Adobe PhotoShop Read Info
Where density drops off.

Observation 1:

Text Box: Density noise is also able to be seen

Text Box: Density Values go up as noise
1,0,1 is now 5,2,6

Observation 2:
