Opto-Electronic Processing Image Group

Ophthalmic applications and physiological optics

Ophthalmic developments are also covered by our group through a double research line. First, the develepment of novel ophthalmic instruments improving capabilities of exsiting ones concerning characterization/visualization/measurement of ophthalmic-related parameters is addressed inside our group. Those ophthalmic instruments can be based on emerging technologies and/or novel applications to the eye of well-know approaches in other research fields. Just as a couple of examples, we have reported on a new measurement device enabling high-precision, noncontact remote and repeatable IOP monitoring based on an innovative measurement principle (secondary speckle pattern tracking) and in a new ophthalmic instrument for visualization and characterization of engraved marks in progressive addition lenses (PAL) based on in-line holography. And second, the group also works in theoretical aspects on physiological and visual optics through the application of advanced mathematical formalisms (power vectors and dioptric power matrices) such as, for instance, astigmatic wavefront propagation, lateral magnification matrix in presence of astigmatism, refractive status prediction from biometric measurements, etc.
