Optical feedback interferometry (OFI) sensors are experiencing a consistent increase in their applications to biosensing due to their contactless nature, low cost and compactness, features that fit very well with current ...

En la comunicación presentamos un dispositivo basado en la deflectometría ronchi digital adaptado para el control de calidad de lentes oftálmicas de adición progresiva, en una sola exposición y a campo completo. Las ...

Per tal d'adaptar les Lents Oftàlmiques a l' Espai Europeu d’ Educació Superior, s' ha endegat una experiència que aplica tècniques d'aprenentatge cooperatiu a les pràctiques de l'assignatura per afavorir el desenvolupament ...

Peripheral refraction, the refractive error present outside the main direction of gaze, has lately attracted interest due to its alleged relationship with the progression of myopia. The ray tracing procedures involved in ...

A non-contact technique for obtaining accurate profiles of optical qualitysurfaces with micrometric accuracy has been developed. The technique isbased on the Ronchi test principle, that is, on the study of the interaction ...
