USAF 1951 Target: Calculating the resolving power of a camera based machine vision system
With the help of the USAF resolution test chart, also called "USAF 1951 Resolving Power Test Target", the resolving power of the machine vision system (camera + lens) could easily be determined.
Resolution = 2Group*+(Element-1)/6 (Line pairs/mm)
One line pair (lp) consists of one black and one white line.
Note: For a simple calculation please select a value from the drop-down box!
Further explanations and details can be found in chapter Limiting resolution and MTF und Resolution of the optics.
