Claim One:
1. An apparatus for imaging an eye, comprising: a multi-wavelength light source configured to emit light to an eye; and a control system configured to: (a) spatially modulate light from the multi-wavelength light source to project a first pattern onto the eye, such that at least one first portion of the eye receives emitted light from the multi-wavelength light source and at least one second portion of the eye does not receive the emitted light from the multi-wavelength light source; (b) receive at an imaging device, at least one first image containing at least one first signal associated with an ocular property of the eye comprising the emitted light reflected from the at least one first portion of the eye; (c) spatially modulate light from the multi-wavelength light source to project a second pattern onto the eye, such that the at least one first portion of the eye does not receive the emitted light from the multi-wavelength light source and the at least one second portion of the eye receives the emitted light from the multi-wavelength light source; and (d) receive at the imaging device, at least one second image containing at least one second signal associated with the ocular property of the eye comprising the emitted light reflected from the at least one second portion of the eye; wherein: the at least one first signal is optical wave interference of specularly reflected light from an ocular tear film combined with at least one background signal; and the control system is configured to receive the at least one first image by being configured to: capture a first tiled pattern of the specularly reflected light including the at least one background signal from the at least one first portion of the ocular tear film in the at least one first image by the imaging device; and capture a second tiled pattern of the specularly reflected light including the at least one background signal from the at least one second portion of the ocular tear film in the at least one second image by the imaging device.
