Claim 23:
24. An optical sensor comprising:
a planar sensor array;
a lens configured to form an optical image on the planar sensor array, wherein a locus of focal points of the lens is on a curved surface; and
a cover glass on the planar sensor array and including a first planar region and a second planar region, wherein the second planar region of the cover glass has a higher thickness or a higher refractive index than the first planar region of the cover glass and is configured to shift a first portion of the locus of focal points of the lens such that a middle region of the first portion of the locus of focal points intersects the planar sensor array at one or more points and peripheral regions of the first portion of the locus of focal points do not intersect the planar sensor array;
wherein at least two points of the first portion of the locus of focal points on opposite sides of an intersect point of the first portion of the locus of focal points and the planar sensor array are on opposite sides of the planar sensor array.
