MTF Analysis Slant Edge Scanner Target with Grayscale SFR & OECF

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

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

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).

Substrate Size: 75 x 95mm

Substrate Type: White reflective photo-paper White reflective photo-paper : Photographic emulsion Polarity: emulsion Polarity

Reading Direction: Right Read Emulsion Up (RREU). Image Placement Accuracy: Not applicable

Feature Size Accuracy: Not applicable Image Contrast / Density: Not applicable

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) is available for download from www.i3a.org. 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.
