À la Librascope, filiale de Singer, un afficheur polychrome exploite la transition smectique-nématique dans un cristal liquide chauffé. Chaque cellule est associée à un filtre coloré rouge ou vert; deux cellules et deux filtres permettent de réaliser une image en rouge, vert et jaune par mixage ou en noir, les deux cellules diffusant alors la lumière. On a obtenu des images colorées de haute résolution de 2 048 X 2 048 points en chauffant très localement les deux lames de cristaux liquides à l'aide d’un fin pinceau laser Yag balayant l'écran. 1, record 1, French, - transition%20smectique%2Dn%C3%A9matique

L'albédo géométrique est le rapport de l'intensité lumineuse réfléchie vers l'observateur à celle reçue par la planète, pour un angle de phase nul, c'est-à-dire lorsque la planète est en opposition(soleil, observateur et planète alignés, donc phase pleine). On le définit aussi comme le rapport de la brillance du disque planétaire à l'angle de phase nul, à la brillance d’un disque parfaitement diffusant(agissant donc comme un écran blanc) et de même taille. On peut aussi le définir dans une bande passante restreinte ou au contraire sur tout le spectre. 3, record 3, French, - alb%C3%A9do%20g%C3%A9om%C3%A9trique
