SU34611A1 - Screen for receiving vision - Google Patents

Description

The present invention relates to

I screens for TVs and serves for

continuous linear transformation

The movement of the light of the element of the illumination {point in a variable brightness).

The screen consists of two parallel to each other, rows of cylindrical ;; inz, located on the path of the beam and the width of each element of the image, and a matte screen placed between the specified rows.

In FIG. 1 and 2 are an image of a screen in two projections. The latter consists of two continuous rows of links / and 2, spaced from each other at a distance equal to the sum of the focal lengths of the first and second row lenses, and at the focus distance between the lenses there is a matte screen 5, and the individual lenses are fenced off from each Other by light-penetrable walls 4. A parallel light beam 5 emitted by some light element of the transmitted image and moving along one row of lenses) for example row 2 gives a series of flashing boiling illuminated spots 6 on the screen 3, which via a number o vtopo lens / are converted into parallel light beams 7.

Thus, in this device, a moving beam of light is transformed into a continuous series of consecutively flashing fixed beams of light.

The dimensions of the lenses and their number are determined by the required number of nepepfeiv light and the duration of individual flashes.

A necessary condition for the operation of the device, with a constant distance between the lenses, is the parallelism of individual rays in the primary light beam.

The subject matter of the invention.

A screen for receiving vision, characterized in that, in order to transform a continuous linear motion of the luminous image element into a dotted variable luminance, two parallel to each other rows of cylindrical lenses equal in width | The image element, between which a matte screen is located.
