Abstract:
1. A multifocal capable ophthalmic aberrometer, comprising: an afocal relay defining an optical axis, an object plane, and an image plane, wherein said image plane is conjugated to said object plane; a probe beam projected along said optical axis and propagating toward said object plane, wherein reflection of said probe beam from a subject eye located at said object plane generates a wavefront emerging from said object plane; a Hartmann-Shack sensor positioned at said image plane and producing an image of Hartmann-Shack spots of said wavefront; a control electronics acquiring a plurality of said images of said Hartmann-Shack spots in a single measurement; and a processing electronics calculating an optical power map of said subject eye with respect to a center of said wavefront and averaging said optical power map over said plurality of said images, wherein said processing electronics comprises:
