Abstract
IL S'AGIT D'UN DISPOSITIF COMPORTANT, EN COMBINAISON, UNE PLATINE PORTE-TESTS 14, DEUX VOIES OPTIQUES DISTINCTES PROPRES CHACUNE A FORMER UNE IMAGE D'UN TEST PORTE PAR CETTE PLATINE, ET UN POSTE D'OBSERVATION 11 ACCESSIBLE A UN SUJET ET PROPRE A PERMETTRE A CELUI-CI L'OBSERVATION D'UNE TELLE IMAGE. LES DEUX VOIES OPTIQUES COMPORTENT CHACUNE RESPECTIVEMENT DES MIROIRS DE RENVOI 25, 26, ET UN MIROIR 22, MOBILE DANS SON PLAN, PERMET DE PASSER DE L'UNE A L'AUTRE; LES DISTANCES D'OBSERVATION SUIVANT LESQUELLES LE SUJET CONCERNE VOIT L'IMAGE DU TEST EN PLACE SONT ALORS DIFFERENTES L'UNE DE L'AUTRE. APPLICATION A LA SOLLICITATION EN ACCOMMODATION OU EN CONVERGENCE D'UN QUELCONQUE SUJET.
