Zöll·ner lines (tsōrl'nĕr), figures devised to show the possibility of optic illusions; a common one consists of two parallel lines that are met by numerous short lines obliquely placed; the parallel lines then seeming to converge or diverge.Zöll·ner lines (tsĕrl'ner līnz) Figures devised to show the possibility of optic illusions; a common one consists of two parallel lines that are met by numerous short lines obliquely placed, the parallel lines then seeming to converge or diverge. Zöllner linesParallel lines, usually three long ones, with a series of short lines drawn at regular intervals across one of the lines at approx. 60 degrees. Similar lines are drawn across the second line at the angle of approx. 120 degrees. Short lines are drawn across the third at the same angle as on the first lines. These lines produce the optical illusion that the long lines are converging or diverging. See also: lineZöllner, Johann F., German physicist, 1834-1882.
