Pincushion distortion from spherical detectors

  1. Feb 14, 2012 #1
    I'm wondering how the use of spherical shaped detectors causes pincushion distortion. I can understand the shape of the detector affecting the final image but I thought the lines would bend out as when a hemisphere is laid out flat, a point appearing near the center from the front on angle would appear further away when the detector is flat. However every image of pincushion distortion has the lines bending in.

    Can you provide some context? I'm more familiar with field curvature in this regard.
