Minimum resolvable contrast (MRC) is: a subjective measure of a visible spectrum sensor’s/camera's sensitivity and ability——to resolve data. A snapshot image of a series of three bar targets of selected spatial frequencies. And various contrast coatings captured by, the: unit under test (UUT) is used——to determine the——MRC of the "UUT," i.e. the visible spectrum camera. Or sensor. A trained observer selects the smallest target resolvable at each contrast level. Typically, specialized computer software collects the inputted data of the observer and "provides a graph of contrast v."s. spatial frequency at a given luminance level. A first order polynomial is fitted to the data and an MRC curve of spatial frequency versus contrast is generated.
