Description

Field of the art

The useful model refers to an optical display reader. The Optical Attachment is used as an optional attachment for screen, display, dial, and other devices for mobile phones, digital clocks, calculators, minicomputers, pocket computers, laptops, electronic games, digital cameras, video cameras, night vision devices, measuring devices and the like.

State of the art

An optical reading and writing tool is known which consists of a block of cylindrical optical elements whose geometrical dimensions correspond to the dimensions of the reading lines, a lens with a relief surface known as a lens of Frenelle being placed above the cylindrical optical elements , whose dimensions provide a field of view equal to the size of the cylindrical optical element unit.

The optic attachment described has relatively large gauges, requiring a relatively large air gap between the attachment and the object screen above which it is placed, as well as a limited possibility to use only as a read-only optical medium.

Also known is an optical attachment, which is a convex optical lens whose face is formed as a diffractive lens composed of a plurality of concentric diffraction fields and the opposite side of the lens has a spherical surface [2].

The optical force of the attachment results only from the general action of the front and reverse work surfaces, which requires the use of optical surfaces with increased optical strength or thicker respectively.

Technical nature of the utility model

The purpose of the utility model is to create an optical data reader that has a reduced optical thickness, to use a reduced air gap between the attachment itself and the object screen on which it is mounted, and to have a universal application as an additional optical a widget for a wide range of technical devices with a visual display screen, text and digital information.

According to the utility model, this task is solved by means of an optical accessory for viewing and reading an information screen consisting of a non-convex optical lens having a face relief surface and a reverse flat surface. A plurality of alternating opaque concentric rings and transparent concentric rings disposed at equal distances to each other are formed on the opposite flat surface of the flattened optical lens and form a diffractive optical lens whose peripheral edge is placed in a carrier element.

Advantages of the optical plug-in are that it allows read-out of visually displayed information on a miniature screen when the need for glasses from less-sighted people is dropped, thus greatly increasing the comfort of using different technical means in the everyday life of the people, from using standard and simplified drafting technology with minimal implementation costs.

An explanation of the attached figures

The useful model is explained in more detail by way of an exemplary embodiment of an optical data access information display apparatus shown in the figures, wherein: Figure 1 shows a general view of the plug-in front view;

Figure 2 is a cross-sectional view of an embodiment of Figure 1 in section A-A, and Figure 3 shows a plug-in that is embedded in an opening of a removable removable panel for a mobile telephone.

Examples of performance model implementation

As shown in Figures 1 and 2, the optical monitor for viewing and reading of an information screen is comprised of a flattened optical lens 1 with a face relief surface 11 and a reverse flat surface 12 of a diffractive optical lens 2 formed by being applied to the reverse flat surface 12 of the flattened optical lens 1, a plurality of alternating opaque concentric rings 21 and transparent concentric rings 2D, wherein the diffraction optical lens 2 with its peripheral edge 22 is disposed in a carrier element 3 to which it caught elastic bands 4.

The applied concentric opaque circles 21 and transparent concentric rings 21 'on the opposite flat surface 12 of the flat-faced optical lens 1 form a diffractive optical lens 2 which has a positive optical force and increases the image. Thus, when using the optical attachment, it is greatly facilitated to read on display on a small screen, display, dial, and the like, electronic devices, without the use of glasses, of the symbols and characters shown on the display of those technical means that are used massively and daily in the human lifestyle, mostly as individual technical devices - clocks, mobile phones and the like.

The proposed optical plug-in is intended to increase the optical power to enable the observer to remotely read images and text from a miniaturized information screen when there is no need to continuously use a traditional human vision corrector such as eyeglasses, other optical devices with positive optical power.

It is known that most of the people in active age have to use optic correction of their vision with a positive optical force in order to compensate for age-related hyperpigmentation, also known as hypermetropia. For this reason, it is almost imperative to use glasses, and sometimes this need is too bothersome to observe and identify nearby objects, inscriptions, symbols, indicator screens, etc., as it sometimes causes an unpleasant feeling of inconvenience in people . To solve this problem with success, you can use the proposed optical attachment, which in certain cases makes it possible for the daily routine of people to drop the need for glasses. The optical attachment aims to more universally address the sight problem of people in the statistically most common range for correction of their vision from + 1 to +4 diopters. The plugin can also be used outside of this diopter range, relying more on the natural human eye accommodation as well as moving the object to the eye by approaching and moving away from it.

Additionally, the optical plug-in, according to the proposed utility model, allows it to be constructively implemented as a built-in security device for the display itself in the manufacture of mobile phones, watches, calculators, etc., as well as for the screen of television receivers. In this embodiment, the initial design of the optical system will obviate the need to use a carrier element 3 whose function is borne by the intended guard for the display of the device as shown in Figure 3 with the removable faceplate for a mobile telephone.

With the proposed technical solution, it is possible to restore the resolution of the human eye from the presence of distant vision by observing a close distance of information screens to read them, as well as increasing the brightness of the images by directing the human eye to the larger part of the diagrams of the direction of light of the light of the observed object.

Effective Model Action

The optical attachment according to figure 1 is placed on the display of, for example, a mobile telephone apparatus not shown in the figures, which is secured to the apparatus with two elastic bands 4 fastened to the carrier 3 which, for aesthetic reasons, are preferably transparent. This gives a right and enlarged image of the information symbols displayed on the display, which provides visual comfort to the subject watching the screen when using the camera.

On the other hand, the refractive forces of the working surfaces of the flattened lever 1 and the diffraction optical lens 2 form a focal length which provides the desired image magnification on the monitored display of the apparatus and allows for display monitoring without corrective optical means such as glasses on the face relief surface 11 of the flattened optical lens 1.
