Abstract
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.
