DEVICE AND METHOD FOR RAY TRACING WAVE FRONT CONJUGATED ABERROMETRY

摘要

Step 2 of raytracing is measured continuously probing beam entering the eye parallel to the optical axis, a preliminary step of, and probing beam entering the eye is continuously doedoe a main measurement step of flowing is inclined in a manner to compensate for a variety of inlet aperture over the refraction measured in a preliminary step. The main steps of the measurement can be performed in the combination of units, one is compensation for the defocus other is a compensation for the higher order aberrations. In one embodiment, the probe beam is two having the collimator lens between the two-coordinate acoustic-optical deflector includes groups. Is the main step of the measurement procedure can be repeated over and over again until the achievement accuracy wavefront tracing rules.
