The target is situated in a night sky luminous environment of level less than or equal to 4. Use is made of an imaging device of focal length f and of pupil diameter D, comprising at least one detector comprising types of pixels configured to operate in the wavelength region lying between 1 μm and 1.9 μm, the detectors exhibiting a noise level of less than 0.6×1015/(f/D)2, and from the image obtained by this device is extracted at least one negative-contrast zone, that is to say a black zone on a bright background corresponding to the presence of the target in the night sky of level less than or equal to 4."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of imaging a target in a night sky","description":"A method is provided for detecting a target not emitting in the wavelength region lying between 1 μm and 1.9 μm.
