ABSTRACT:
An optical system deviation estimating apparatus includes an erected/inverted attitude setting means9for changing dispositional attitude of an optical system under test, a non-interferometric type wavefront measuring means10for measuring wavefronts at the attitudes as set up without resorting to interference phenomenon of light, a polynomial approximation means15for expanding measured wavefront values determined by the non-interferometric type wavefront measuring means10to a polynomial, an averaging arithmetic means11for averaging the measured values derived from output of the non-interferometric type wavefront measuring means10or alternatively arithmetic values derived from output of the polynomial approximation means15, and a polynomial specific coefficient extraction arithmetic means16for extracting specific coefficient values of the polynomial.
