Title (EN) PROCESS AND EQUIPMENT FOR RECORDING AND DISPLAYING LASER INTERFERENCE IMAGES
(FR) PROCEDE ET INSTALLATION D"ENREGISTREMENT ET D"AFFICHAGE D"IMAGES PAR INTERFERENCE DE LASER
Abstract: front page image
(EN)Process and equipment relate to recording and displaying stationary or moving laser interference and so-called preholographic, respectively, images or image sequences in a predetermined order of sequence. The essence of the process lies in that the images or image sequences to be displayed are produced by the proper formation of the single surficial parts of the plate and the sequential illumination of said parts by the laser light. In case of moving images or image sequences either the plate or the bundle of laser is suitably moved... The essence of the equipment lies in, that the equipment is provided with a laser source, an intercepting screen and between the laser source and the intercepting screen there is a plate arranged. By means of optical elements (e. g. lenses and lens systems) arranged between the plate and the screen and the laser source, respectively, the interference images can be further intercepted.
(FR)Procede et installation d"enregistrement et d"affichage d"images stationnaires ou en mouvement d"interference de laser et d"images ou respectivement de sequences d"images qu"on appelle preolographique dans un ordre de sequence predetermine. Le procede consiste essentiellement en ce que les images ou sequences d"images a afficher sont produites par la formation proprement dite de chaque partie de surface de la plaque et par l"eclairage sequentiel desdites parties par la lumiere du laser. Dans le cas d"images en mouvement ou de sequences d"images la plaque ou le faisceau de rayon laser est deplace convenablement. L"installation se caracterise en ce qu"elle est pourvue d"une source de laser, d"un ecran d"interception et une plaque disposee entre la source de laser et l"ecran d"interception. Au moyen d"elements optiques (par exemple des lentilles et des objectifs) disposes entre la plaque et l"ecran et la source de laser respectivement, les images d"interference peuvent etre interceptees ulterieurement.
