Abstract

An optical system deviation estimating apparatus includes an erected/inverted attitude setting meansfor changing dispositional attitude of an optical system under test, a non-interferometric type wavefront measuring meansfor measuring wavefronts at the attitudes as set up without resorting to interference phenomenon of light, a polynomial approximation meansfor expanding measured wavefront values determined by the non-interferometric type wavefront measuring meansto a polynomial, an averaging arithmetic meansfor averaging the measured values derived from output of the non-interferometric type wavefront measuring meansor alternatively arithmetic values derived from output of the polynomial approximation means, and a polynomial specific coefficient extraction arithmetic meansfor extracting specific coefficient values of the polynomial.
