Since the dome is spherically symmetric, every object at infinity will produce a virtual image at the same distance from the dome, regardless of the object's direction. Hence, 'infinity' is mapped onto a sphere that is concentric with the dome but has a larger radius. Extended objects that are closer than infinity produce virtual images that are more flattened, but still wrapped onto a curved surface." -- this is the specific quote from the link above. Perhaps "distorted" is the better phrase? | |
| Apr 11, 2018 at 4:45 | comment | added | Cardinal Sine | I assume that by curved you mean it's distorted. Distortion is one of a few primary aberrations of an image that are unavoidable when imaging with spherical or cylindrical lenses. Anyway, there's no preferred image for distortion to take effect. Real and virtual images can be distorted and prettry much the same manner. | |
