Minimum resolvable contrast

The minimum resolvable () is a measure of the sensitivity and resolution of a visible or .

The unit under test (), which is the visible or , is utilized to take a snapshot image of a of three bar targets with a variety of coatings and specified spatial frequencies.

The smallest target that can be resolved at each level is chosen by a trained observer.

The observer's is often collected by specialized , which then outputs a of vs. spatial at a certain level.

The are fitted with a first order , and an plotting spatial vs is produced.
