Abstract
An emitter emits a wavelength included in the visible and/or infrared spectrum to illuminate a scene. An observation system is configured to deliver an image representative of the illuminated scene to an observer. The emitter is configured to deliver a light emission by at least one flash with a luminous power greater than a threshold generating dazzling. The observation system presents a first operating condition and a second operating condition of the observed scene to the observer, the second operating condition transmitting less luminous power than the first operating condition. A synchronization circuit is configured to synchronize the emitter and the observation system so that the observer is not dazzled during the emission phase of the emitter.
