Title (EN) IMAGING DEVICE AND METHOD UNDER STRONG ATMOSPHERIC SCATTERING CONDITION
(FR) DISPOSITIF ET PROCÉDÉ D'IMAGERIE SOUS CONDITION DE DIFFUSION ATMOSPHÉRIQUE FORTE

Abstract:
(EN) An imaging device under a strong atmospheric scattering condition for imaging a target object (60) through a scattering medium (70), comprising: a laser (10), a spatial light modulator (20), a first lens (30), a second lens (40), and an image sensor (50). The spatial light modulator (20) comprises multiple flipable micro mirrors; the spatial light modulator (20) is disposed on a path of laser emitted by the laser (10); the path of laser is reflected by the micro mirrors of the spatial light modulator (20), then is transmitted through the first lens (30) to reach the target object (60) through the scattering medium (70); and then the path of laser is reflected by the target object (60) and passes through the scattering medium (70), then is transmitted by the second lens (40) to reach the image sensor (50) to image the target object (60). Further provided is an imaging method under a strong atmospheric scattering condition. The imaging device and method under a strong atmospheric scattering condition greatly improves imaging quality under a strong atmospheric scattering condition.
(FR) L'invention concerne un dispositif d'imagerie visant à imager, dans une condition de diffusion atmosphérique forte, un objet cible (60) à travers un milieu de diffusion (70), le dispositif comprenant : un laser (10), un modulateur spatial de lumière (20), une première lentille (30), une seconde lentille (40) et un capteur d'image (50). Le modulateur spatial de lumière (20) comprend de multiples micromiroirs commutables ; le modulateur spatial de lumière (20) est disposé sur un chemin optique de lumière laser émise par le laser (10) ; le chemin optique de la lumière laser est réfléchi par les micromiroirs du modulateur spatial de lumière (20), puis est transmis à travers la première lentille (30) pour atteindre l'objet cible (60) à travers le milieu de diffusion (70) ; puis le chemin optique de la lumière laser est réfléchi par l'objet cible (60) et traverse le milieu de diffusion (70), puis est transmis par la seconde lentille (40) pour atteindre le capteur d'image (50) pour imager l'objet cible (60). L'invention concerne en outre un procédé d'imagerie dans une condition de diffusion atmosphérique forte. Le dispositif et le procédé d'imagerie sous une condition de diffusion atmosphérique forte améliorent considérablement la qualité d'imagerie dans une condition de diffusion atmosphérique forte.
