SU75779A1 - Reflective screen - Google Patents

Description

Offers screen for daytime cinema, equipped with a translucent layer and a mirror layer behind it.

A distinctive feature of the proposed screen is that the translucent and mirror LAYERS of the screen are formed on two transparent plates made one after the other, corrugated, which increases the angle of view of the screen and ensures uniform dispersion of the reflected light.

The screen plate configuration is shown in FIG. one; in fig. 2 is a diagram of the reflection of rays from the screen.

The back plate / a (FIG. I) is covered with a FLAT mirror layer, and the front plate 16 with a translucent layer 2 in the form of a raster. The gaps between the raster elements are covered on the reverse side of the plate 16 with a mirror layer 4.

The light from the projector 3 {FIG. 2) falls onto the plates / a and 16 and is reflected from their corrugated surfaces at an angle of view greater than D1, a: l at the usual screen; this ensures uniform light diffusion throughout the auditorium; Thus, the corrugation step is changed, the desired angle of reflection can be obtained.
