Abstract: A range of a wavefront sensor is extended by focusing collimated light onto a lenslet array, an output creating a grid formed by edges of the lenslets and a reference spot in the members of the grid. Each reference spot has a known relationship to the grid member and a centroid. A relationship between the reference centroids is determined. Next a wavefront emanating from an eye is focused onto the lenslet array, with the output from the lenslet array forming the grid and aberrated eye spots thereon, each eye spot having a centroid. A relationship between the eye spot centroids is determined. One known relationship between one reference centroid and the centroid of one eye spot is identified. Finally, at least some of the remaining relationships between the reference centroids and the eye spot centroids are determined. The determined relationships provide a measure indicative of the eye aberration.
