Abstract

The present device relates to stereoscopy, namely to devices for viewing a three-dimensional image of the parallel stereopair type. Parallel stereopair is a type of stereo image representation, in which the images for the left and right eyes of the observer are located on the carrier one next to the other, respectively, on the left and right. The problem to which the claimed technical solution is directed is to obtain an inexpensive technological stereoscope for high-quality viewing stereopairs on cards and smartphones of different sizes, the dimensions of which in the initial state allow you to put it in magazines and booklets. The design of the stereoscope includes a flexible elastic thin-walled plate, a panel for holding eyepiece lenses, eyepiece lenses, a carrier of a stereopair. holds the carrier of stereopairs and a flat panel with eyepiece lenses in parallel planes. Changing the bending curvature of the plate allows you to set carriers of stereopairs of different sizes. To increase the range of sizes of carriers of stereopairs, flexible elastic plate can be made composite. Dividing the elastic plate into parts allows to reduce the dimensions of the stereoscope in its initial state. The lenses have the ability to move along the panel on which they are installed. This is how the lens distance is adjusted. Coarse adjustment of the focal length is carried out by means of the variable installation of the lens panel into the suitable mounting slots on the elastic plate, of which there are several. Precise adjustment of the focal length is carried out by bending the panel with the lenses. Assembly of the stereoscope is carried out using protrusions, slots, grooves and foldable valves without fasteners or adhesives. Disassembled stereoscope is compact and easy to store and carry.

Description

The present device relates to stereoscopy, namely to devices for viewing a three-dimensional image of the parallel stereopair type. Parallel stereopair is a type of representation of a volumetric image in which the images for the left and right eyes of the observer are located on the carrier one next to the other, left and right respectively.

Many designs of collapsible and collapsible lens stereoscopes for viewing parallel stereopairs are known from the prior art. An example is the constructions described in applications for a utility model - RU 45196 U1, RU 32894 U1 and others.

The task to achieve which the claimed technical solution is aimed at is to obtain an inexpensive, technologically advanced stereoscope for high-quality viewing of stereopairs on cards and smartphones of different sizes, which can be used for advertising purposes - to invest in magazines and booklets, use in conjunction with handouts at exhibitions; with which you can view personal stereo photos; which can be sold as a souvenir, complete with a collection of stereo photographs in museums and tourist attractions; use in virtual reality applications, etc.

A stereoscope made in accordance with this utility model is characterized by a combination of the following features:

can be made from inexpensive sheet material in a single process, such as punching or laser cutting.

in its original state it has dimensions that allow it to be inserted into magazines and advertising brochures, see FIG. one.

has the necessary settings for comfortable viewing of the image - setting the focal length and setting the lens distance;

allows you to view images on cards with a rigid base or on the screen of a small display, such as a smartphone.

allows you to use carriers of stereopairs of different sizes, for example smartphones with different screen sizes.

when using a smartphone as a carrier of a stereopair, the details of the stereoscope design do not impede access to the screen and other controls, which allows using the smartphone for its intended purpose without removing it from the stereoscope, see Fig. 2. If a transparent material is used to make a stereoscope, a smartphone camera can scan a QR code to quickly find stereo images on the Internet or read text comments, also without removing the smartphone.

When viewing stereopairs on cards, the open design of the stereoscope allows the maximum amount of light to penetrate the image, especially if the stereoscope material is transparent.

The assembly of the stereoscope is carried out without fasteners or adhesives, only with the help of protrusions, slots, grooves and folding valves.

Stereoscope construction, see FIG. 2, includes a flexible elastic thin-walled plate 1, a panel for holding eyepiece lenses 2, eyepiece lenses 3, a stereo pair carrier 4.

Flexible elastic plate 1, which is bent when assembling the stereoscope, allows, by changing the curvature of the bend, to hold different sizes of carriers of stereopairs 4. Holding occurs by means of valves 1a, which are part of the elastic plate and are bent at a certain angle during the initial assembly of the stereoscope. To increase the range of sizes of carriers of stereopairs, the flexible elastic plate can be made composite, with the ability to fix parts with different displacement relative to each other. Dividing the elastic plate into parts allows reducing the dimensions of the stereoscope in its initial state. In addition to the carrier of stereopairs, an elastic plate holds a flat panel with eyepiece lenses, and the carrier of stereopairs and lenses are located in parallel planes.

Focal length adjustment is done in two ways - coarse and fine.

Rough way - variable installation of the panel with lenses into suitable mounting slots on the elastic plate, of which there are several.

The exact method is a slight deflection of the panel with eyepiece lenses, carried out by pressing the observer's nose on the panel.

The eyepiece lenses are installed in the slots of the valves 2a, which are part of the panel 2 and are folded at an angle during the initial assembly of the stereoscope. Slots allow the lenses to slide along the panel, allowing you to adjust the lens distance.

To view the volumetric image, you need to bring the stereoscope with the carrier of the stereopair placed in it to the eyes with the side where the eyepiece lenses are located, holding the entire structure by a flexible elastic plate.

Disassembled, the stereoscope is compact and easy to store and carry, see FIG. 3.
