Computing high order wave aberration coefficients from variations of best focus for small artificial pupils.

摘要: Van den Brink (1962) measured the variation of best focus vertical bar targets through a 1.4 mm aperture across pupil eye. He expressed his results in contour maps isodioptric lines pupil. The relative portion is function curvature wave front within aperture. curvature, turn, proportional to second derivative aberration polynomial. Thus it possible make estimates some coefficients polynomial from Brink's focusing data. This has been done for two states accommodation. indicate that eye contains significant terms power higher than hitherto measured.
