CA 2055592

A device for measuring the response of the eye to the flashing of a luminous source comprises a housing (11) containing a source of electrical energy (16), a light-emitting diode (14), an optical system (15) for focusing the light emitted by the source on the retina of the eye and an electronic control device (17). This device is arranged to generate numerical sinusoidal signal with modulation delta, which simplifies the circuit and ensures that the measurements are sufficiently stable.

2055592 9114399 PCTABS00106 Cet appareil qui permet de mesurer la réponse de l' il aux clignotements d'une source lumineuse, comporte un boîtier (11) contenant une source d'énergie électrique (16), une diode photoémettrice (14), un système optique (15) pour focaliser la lumière émise par la source sur la rétine de l' il et un dispositif de commande électronique (17). Ce dispositif est agencé pour engendrer un signal sinusoïdal numérique en modulation delta ce qui simplifie le circuit et donne suffisamment de stabilité aux mesures.
