The optical resolving power of the scanner based imager. (Left) 1951 Air Force test target scanned with 4800 dpi mode. (Top Right) Zoomed in region of the same image. The smallest resolved line-width is 7.8 μm along the sensor direction and 12.4 μm along the scanning direction. (Insets) The cross sections of the resolved grating lines are shown. 8× interpolation was used for better visualization of the resolution test.
