Abstract

Dispositif permettant de mesurer l’émission angulaire d’une source, sans mouvement mécanique, caractérisé en ce qu’il comprend, successivement selon son axe optique : un premier objectif, dit de Fourier (2), agencé pour former une surface de Fourier (3) dont chaque point correspond à une direction d’observation de l’objet ; un diffuseur (8) utilisé en transmission et disposé sur la surface de Fourier ; une densité optique (12) disposée en amont du diffuseur et agencée pour atténuer la lumière rétrodiffusée vers l’optique de Fourier 2 et ladite source étendue ; un vidéo-photomètre (9) situé en aval du plan diffuseur (8) et agencé pour imager la surface du diffuseur. Figure pour l’abrégé : figure 7
