Ophthalmic instrument having wavefront sensor with multiple imaging devices that simultaneously capture multiple images of an array of spots produced by a lenslet array

An ophthalmic instrument comprising:

• a wavefront sensing illumination source for producing light formed as a spot image on the retina of a human eye and reflected from said human eye;
• and
• a wavefront sensor for estimating aberrations in reflections of the light formed as a spot image on the retina of said human eye,
• said wavefront sensor including a beam splitter operably disposed between a lenslet array and multiple imaging devices, and said lenslet array forming a first array of spots, and said multiple imaging devices capturing multiple images of said first array of spots for use in estimating said aberrations;
• and
• a phase compensator, operably coupled to said wavefront sensor, for spatially modulating the phase of incident light to compensate for said aberrations estimated by said wavefront sensor.
