SU98411A1 - A device for determining the nature of vision - Google Patents

Description

The well-known 11) And (1 & |) s for determining the character, vision n)) and open eyes, for example, diplomas, make it possible for Hocib to carry out the required research only at a certain, predetermined setting (i5f, from the eye of the observed object. based on the mechanical separation of the zoological view of both eyes.

The peculiarity of the predloktennogo .Hjiiulopa is in T (: i, that to separate the fields of vision of the right and left eye in it is attached to the system of olivine or other zero) OIDs.

This feature is both; -It excludes the possibility of studying the vision of the orthoiotic treatment of squint at any practically necessary distance from the eyes to the observed object. a more correct judgment about xapaiiTepe of the vision and achievement of the comic factor.

FIG. 1 has been shown; the OITIC scheme of the instrument has been changed; iia FIG. 2 is a schematic representation of an acraia with I1) a dark ilastine.

The proposed device is made in the form of a black-painted screen (1) with holes in (2), (3), (4) and (5), irred with polyvinyl or other polaroids (G), (7), (8) and (9) with mutually inpendicular polarization planes. Behind. iolomides of Iomei; een transparent ilastin (10). It is illuminated by natural IL1G artificial light, for example, an E.Spectric lamp (11).

On the letter (well, (10) there are letters, rasiolo; ... in the field of holes (2), (3). (4) and (5.).

Before the eyes (12) and (13) of the observers, the polaroids (14) and (13) are installed with the perceptual polarisations of the polarization planes, together with the polarization planes of the polaroids (7) - (9) and (6) - (8), covering the iiiUix holes (3) - (5) and (2) - (4) of the screen (1).

When the lamp is illuminated (the screen (1), the observer will see: with his left eye (12) holes (3) n (5), and his right eye (13) - from) (2) - (4). The remaining two openings | ti for kdpgo laza soltots. With a black background ;-) edges) a and) ie will therefore be visible.

If from the side of the light source to the screen (1) attach a transparent plate (TO) (Fig. 2) with inscribed letters on it, for example, water, so that the letters ghsali in the corresponding hole, then the observer with the left eye

(12) will see the letters (0) and (A) (diplogram of the left eye), and the right eye

(13) - the letters (B) and (D) (diylogram i) aBoro eyes).

But the results of the form of the first observer. Rationalized the letters of 5 it is possible to judge the nature of the sight with two open eyes.
