Catalog Part No: QA-62- SFR-P-RM

Product Name: Slant Edge Scanner Target with Grayscale SFR & OECF #2

Drawing / Photo of Part: 

Description: Dark grey 25mm square rotated 5 degrees (CW) on a grey field. Surrounding grayscale patches change in discrete steps from white to black. Twenty patches are provided, measuring 9x9mm each. The four corner-crosses measure 2.625" (66.68mm) center to center. The upper right grayscale patch is equal in density to the background of the rotated square (0.50 density). The lower left grayscale patch is equal in density to the center rotated square (1.10 density).

History / typical use: Test Chart is used to check response of digital systems to the slanted sharp edge step function, an MTF analysis.

Other: A Windows executable program (2.5 MB zip file).That executable is a target format specific version of sfrwin that allows the user to easily select fiducial mark locations through a GUI. Four SFR estimates (two horizontal and two vertical) are generated based on pre-defined edge locations as well as Opto-Electronic Conversion Function (OECF) and noise data for target gray patches. TIFF and BMP files are the acceptable input formats.
