Claim 0:
1. An ocular aberrometry system comprising:
a wavefront sensor configured to provide wavefront sensor data associated with an optical target monitored by the ocular aberrometry system; and
a logic device configured to communicate with the wavefront sensor, wherein the logic device is configured to:
determine a complex analysis engine for the ocular aberrometry system based, at least in part, on an aberrometer model and/or an eye model associated with the ocular aberrometry system, wherein the aberrometer model and the eye model are based, at least in part, on wavefront sensor data provided by the wavefront sensor;
generate a compact analysis engine for the ocular aberrometry system based, at least in part, on the determined complex analysis engine;
generate the eye model associated with the ocular aberrometry system, wherein the generating the eye model comprises:
illuminating at least the wavefront sensor of the ocular aberrometry system via a double pass model target arranged as the optical target monitored by the ocular aberrometry system;
varying a position and/or orientation of an interchangeable ocular aberration model of the double pass model target, relative to an optical axis of the ocular aberrometry system, according to a plurality of selected alignment deviations to generate a corresponding plurality of sets of wavefront sensor data provided by the wavefront sensor; and
storing the plurality of selected alignment deviations and the corresponding plurality of sets of wavefront sensor data as the eye model; and

determine the complex analysis engine based, at least in part, on the generated eye model.
