Abstract

a. Dispositif optique de déviation permettant de faire varier la direction d'un faisceau de rayons lumineux. b. Ce dispositif est constitué d'une série de prismes 1, 2, 3 disposés côte à côte et dont chacun comporte une face externe tournée dans l'une des directions prévues de réception ou d'émission et une autre face sensiblement parallèle à une face du prisme voisin, mais écartée de celle-ci pour former un intervalle 4 ou 5. Ce dernier renferme, ou est susceptible de recevoir, un fluide apte à modifier les conditions physiques de passage des rayons lumineux, soit pour permettre leur libre transmission d'un prisme à l'autre, soit pour les réfléchir à l'endroit d'un tel intervalle, l'orientation du ou des intervalles ainsi prévus étant déterminée en fonction de la ou des déviations à réaliser. c. Le présent dispositif peut être utilisé dans divers appareils optiques, photographiques ou cinématographiques, soit pour dévier un faisceau de rayons lumineux afin de le diriger vers l'une ou l'autre de plusieurs directions prévues de réception, soit inversement pour diriger, vers une direction déterminée, un tel faisceau provenant de l'une ou l'autre de plusieurs directions possibles d'émission.at. Optical deflection device for varying the direction of a beam of light rays. b. This device consists of a series of prisms 1, 2, 3 arranged side by side and each of which has an outer face turned in one of the intended directions of reception or emission and another face substantially parallel to a face of the neighboring prism, but separated from it to form an interval 4 or 5. The latter contains, or is capable of receiving, a fluid capable of modifying the physical conditions of passage of the light rays, either to allow their free transmission of a prism to the other, or to reflect them at the location of such an interval, the orientation of the interval or intervals thus provided being determined as a function of the deviation or deviations to be produced. vs. The present device can be used in various optical, photographic or cinematographic apparatuses, either to deflect a beam of light rays in order to direct it towards one or the other of several intended directions of reception, or vice versa to direct, towards a direction. determined, such a beam coming from one or the other of several possible directions of emission.
