Description

Wynalazek niniejszy jest przeznaczony do otrzymywania obrazów fotograficznych i kinematograficznych w postaci wypuklej czyli plastycznej i zastosowany byc moze jednakowo w celach reklamowych, rozryw¬ kowych, jak naukowych i mierniczych.Wynalazek wyróznia sie dwoma zasad- niczemi cechami. Jedna z nich jest zastapie¬ nie zwyklego ekranu kinematograficznego przez zespól soczewek, przy pomocy któ¬ rych otrzymuje sie urojony obraz swietlny.Droga zludzenia optycznego osiaga sie w ten sposób w oku ludzkiem wrazenie obra¬ zu stereoskopowego.Druga cecha wynalazku jest to, ze za- pomoca soczewek promienie swietlne, po¬ chodzace z obrazów stereoskopowych, przed utworzeniem w oku ludzkiem obrazu urojo¬ nego lub tez przed rzuceniem obrazu na e- kran, sa juz zmieszane pomiedzy soba. Prze¬ to obrazy stereoskopowe, badz projektowa¬ ne, badz tez tylko mocno oswietlone, sa wy- promieniowane nie w zwyklej postaci swietlnej, a we wspólnej postaci zmiesza¬ nej.Rysunek przedstawia ten bieg promieni w ukladzie optycznym wedlug wynalazku; w punkcie x powstaje obraz plastyczny, u- rojony lub tez rzeczywisty, zaleznie od te¬ go, jak ustawione sa soczewki i co w tern miejscu sie znajduje: ekran lub oko ludzkie.Zaleznie od rodzaju promienie, wysylane z ostatniej soczewki, moga byc równolegle, lub nie.Uklad optyczny moze byc wykonany rozmaicie, przyczem w zaleznosci od roz¬ miarów soczewek i ich wzajemnego oddale¬ nia osiagac mozna rózne wyniki. Obraz uro¬ jony np. moze sie wydawac mniej lub wie¬ cej oddalony od oka widza.Technicznie, w rysach ogólnych, zesta¬ wienie tego ukladu optycznego podobne jest do budowy innych aparatów fotograficznych i projekcyjnych. Sposób dzialania, jak za¬ znaczono ponizej w zastrzezeniach paten¬ towych, znamienny jest tern, iz postacie wy¬ pukle fotograficzne lub kinematograficzne utworzone sa droga oswietlania lub projek¬ cji obrazów stereoskopowych przez odpo¬ wiednio dobrane soczewki. PLThe present invention is intended to obtain photographic and cinematographic images in a convex or plastic form, and it can be used for advertising, entertainment, scientific and surveying purposes in the same way. The invention is distinguished by two essential features. One of them is the replacement of an ordinary cinematographic screen by a set of lenses by means of which an imaginary light image is obtained. The path of optical illusion thus achieves in the human eye the impression of a stereoscopic image. The second feature of the invention is that - with the help of lenses, the light rays coming from stereoscopic images, before forming an imaginary image in the human eye or before projecting the image on the screen, are already mixed with each other. Thus, stereoscopic images, whether designed, or only heavily illuminated, are radiated not in the usual light form, but in a common mixed form. The drawing shows this ray path in an optical system according to the invention; at point x, a plastic, imaginary or real image is created, depending on how the lenses are positioned and what is in this place: the screen or the human eye. Depending on the type of rays, sent from the last lens may be parallel or not. The optical system can be made differently, and different results can be obtained depending on the size of the lenses and their distance from one another. An imaginary image, for example, may appear to be more or less distant from the viewer's eye. Technically, in general, the arrangement of this optical system is similar to that of other photographic and projection apparatus. The method of operation, as noted below in the patent claims, is characterized by the fact that the photographic or cinematographic convex forms are formed by the path of illumination or projection of stereoscopic images through appropriately selected lenses.

Claims

Patent claims. 1. An optical system for viewing convex photographic or kinematographic images, intended simultaneously for the projection of stereoscopic images, characterized by the fact that it consists of two homogeneous convex lenses (a, b), or one lens, positioned in less than their focal distance from stereoscopic films or images and highly illuminated or overexposed, some of the rays emitted from these lenses are focused by means of a third lens (e) whose axis is aligned with the axis of symmetry images and lenses, and which lens is positioned so as to focus only the common rays radiated by the two lenses.

2. System according to claim 1, characterized by the fact that, in addition to three or two lenses (a, b), it has a fourth - (g) or third lens positioned on the axis of symmetry in such a way that its focal point will be of the same length as its distance from the focus point (x) of the rays emitted from the third or second lens, at which point the image is obtained.

3. System according to claim 1 and 2, the characteristic area that an additional lens is placed between the stereoscopic images (c, d) and the two lenses (a, b) so that the rays originating from the stereoscopic images already penetrate these lenses are mixed, so that the real or imaginary image at point (x) wins over clarity.

4. Variation of the arrangement according to claim 1 - 3, characterized by the fact that in the focal point of the lenses (a, b) there are plates or the lenses are spaced apart, the lenses (e, f) are appropriately moved away, so that the images cover up in at point (x), a real superimposed image is produced which is seen on the screen set at that point, or is changed into an imaginary image by adding a suitable lens.

5. Variation of the arrangement according to claim 1 - 4, characterized by the fact that in place of the plates (c, d) cinematographic tapes are placed, the pictures of which are not illuminated simultaneously but one after the other, at the normal rate of change of the kinematic pictures.
