к краю при наблюдении по нормали к выходной плоской поверхности (сплошна  крива  5 на фиг.4)оto the edge when observed along the normal to the output flat surface (continuous curve 5 in figure 4) o

Это происходит вследствие того, что максимум 6 (смофиг.2) И1щикатриссы 7 выходного излучени  дл  периферийных волокон отклон етс  от нормали 8 к вы ходной поверхности 3 экрана, за счет отклонени  падающего светового пучка 9This is due to the fact that a maximum of 6 (fig. 2) I1 of the curtain of output radiation for peripheral fibers deviates from the normal 8 to the exit surface 3 of the screen, due to the deviation of the incident light beam 9

от нормали 1О к входной поверхности экрана 2.from normal 1О to the input surface of the screen 2.

При вьшолнении входной поверхности 5 маткрованной за счет рассе ни  на входном торце волокна происходит расширение светового пучка, попадающего внутрь волокна , и увеличение составл ющей 11 индикатриссы 7 выходного излучени , нор мальвой к поверхности 3.When the entrance surface 5 of the filament is fulfilled by scattering at the input end of the fiber, the light beam that enters the fiber and the component 11 of the indicatrix 7 of the output radiation increases, normal to the surface 3.

Благодар  этому на выходе экрана увеличиваетс   ркость периферийной зоны в направлении по нормали к выходной по верхности {крива  12 на фиг.4}.Due to this, the output of the screen increases the brightness of the peripheral zone in the direction normal to the output surface {curve 12 in figure 4}.

Это  вленна особенно существенно дл  jgrHa.B, когда телесный yi-чэл падающего пучка излучени  значительно меньше входной угловой апертуры волокна, .This is particularly significant for jgrHa.B, when the solid yi-cell of the incident beam is much smaller than the input angular aperture of the fiber,.

Предмет изобретени Subject invention

Просветный экран, выполненный в виде жесткого блока из оптических волокон сIlluminated screen, made in the form of a rigid block of optical fibers with

параллельными ос ми, ограниченного двум  рабочими полированными поверхност ми входной вогнутой и выходной плоской, нормальной к ос м волокон, отличающ и и с   тем, что, с целью повышени parallel axes bounded by two working polished surfaces of the entrance concave and output flat, normal to the axes of the fibers, and in order to increase

| ркости периферийной части выходной поверхности экрана в направлении осей волоj OH , периферийна  часть входной поверхности , охватывающа  ее центральную зону, ограниченную окружностью с радиусом не| the peripheral part of the output surface of the screen in the direction of the axes of the wave OH OH, the peripheral part of the input surface encompassing its central zone bounded by a circle with a radius not

менее трети радиуса сферы, апроксимирующей входную поверхность, выполнена матовой .less than a third of the radius of the sphere approximating the entrance surface is made matte.
