A combination of structured light illumination and a suitable algorithm offers a solution to problems of precision associated with conventional print capture.
If areas of color are very small then standard color-difference equations do not apply and small-angle models should include intraocular scattering of light and retinal-cone topography.
The noted researcher in biomedical optics discusses new imaging techniques involving nanotechnology, plasmonics, and the use of molecular sentinels for biosensing and diagnostics.
