Abstract: An apparatus for determining the refractive characteristics of an imaging system having an inaccessible and diffusive image surface, such as the human eye. Refractive characteristics of the entire wavefront are ascertained by measuring the refractive power of a representative sample of segments of the pupil. By illuminating only a selected segment, the characteristics of each individual segment may be accurately measured using illumination reflected by the diffusive image surface of the subject optical system, and transmitted only through the transmitting segment. Combination of the refractive characteristics of measured segments constitutes the pupil function of the measured optical system, and can be used for a precise determination of corrective lenses. Characteristics of the system measured, including spectral sensitivity and focusing, are also determined.
