| titleOfInvention | Measuring light intensity variations |
| abstract | In the present invention, light variations are measured superimposed on a quantity of background light which varies relatively slowly. To provide the photosensitive element (3, 3') used with a stable operating point, a photo-emitting element (5, 5') is used to inject additional light into the photosensitive element (3, 3'). Thus, the quantity of light injected by this photo-emitting element (5, 5') is selected in such a way that the sum of the ambient light and the injected light is substantially constant. To this quantity of light are added light variations, for example caused by a second photo-emitting element (9, 9'). This method and this device are used in a device intended to measure the eye movements of a person. |
