WebEbook Topic: Rayleigh Criteria: Depth of Focus Book: Field Guide to Optical LithographyField Guide to Optical Lithography WebAs a result of the sensor's anti-aliasing filter (and the Rayleigh criterion above), an airy disk can have a diameter of about 2-3 pixels before diffraction limits resolution (assuming an otherwise perfect lens). However, diffraction will likely have a visual impact prior to reaching this diameter. As two examples, the Canon EOS 20D begins to ...
