1. An apparatus for measuring one or more properties of a cornea, said apparatus comprising:
a first optical system comprising an optical source and a spatial sampling element for generating a converging array of discrete, focused beamlets configured to impinge simultaneously on a plurality of points across at least a portion of a front surface of a cornea; and
a second optical system for:
capturing reflected or scattered light from said front surface and reflected or scattered light from a second surface or interface of said cornea;
measuring relative phase between the reflected or scattered light from said front surface and the reflected or scattered light from said second surface or interface across the portion of said cornea illuminated by said beamlets; and
monitoring said relative phase over time to obtain information on one or more properties of said cornea across the illuminated portion.
