Introduced by the USAF to assure satisfactory and repeatable results for nondestructive testing and to ensure long-term stability of the CR systems, CR Process Control procedures and an associated CR Process Control Standard (CRPCS) were developed. The procedures were placed into T.O.33B-1-2, Nondestructive Inspection General Procedures and Process Controls and the CRPCS has been assigned a National Stock Number (NSN 6635-01-555-4372) and made available to the USAF.
Test Material | Application |
Group Resolution, Type 38, Line Pair Gauge (A and B) | Measuring spatial resolution or un-sharpness |
Contrast Sensitivity Gauge | Contrast sensitivity check |
Centering Target | Central beam alignment |
Afterglow Target | Evaluate CR image for evidence of overshoot or streaking in areas with high density contrast |
Jitter Target | Determine if a lack of smooth movement of the imaging plate and laser scanning device occurs |
Geometric Distortion Markers (4 places) |
Evaluate image to determine if it is distorted in the X and / or Y-axis |
