Description
Изобретение касаетс oiiTir-iecKOio устройства д.1 проекционных установок дневного кино, позво,1 ющего вести 11еп)ерывный комтро.чь за изображением ка экране.The invention concerns the oiiTir-iecKOio device d.1 of the projection installations of the day cinema, which allows you to carry out the information on the screen.
В предлагаемом устройстве между объективом npoci Topa н экраном установлена под углом к оптической осп плоскопараллсльна стекл нна пластинка, наирав.ч юшак часть светового потока проектора на контрольный экран.In the proposed device, between the npoci Topa lens and the screen is set at an angle to the optical axis of a plane-parallel glass plate, forming a portion of the projector's luminous flux onto the control screen.
Как схематически показано па чертеже, свет от источника / направл етс отражателем 2 в фильмовый каиал 3. Под углом к объек1иву 4 установлена плоскопараллельна стекл нна пластипка 5, а за ней расположепо зеркало 6, отражающее световой ноток па экран 7. .За пластинкой 5 смонтирован дополнительный объектив , а за HH:vi установлено зеркало 9, отражающее свет на дополнительный контрольный экран 10 малого размера.As schematically shown in pa in the drawing, the light from the source / is directed by the reflector 2 to film kaial 3. At the angle to the object 4, there is a plane-parallel glass plate 5, and behind it is a mirror 6 reflecting the luminous note of the screen 7. 7. The plate 5 is mounted additional lens, and for HH: vi a mirror 9 is installed, reflecting light on an additional control screen 10 of small size.
Световой поток, выход щий из обт ектива 4 и падающий на плоскопараллельную пластинку J, раздел етс ею па две Macjii. Больша часть светового нотока (QO/fc) проходит через пластинку 5 и зеркалом 6 отбрасываетс на рабочий экран 7; меньща часть (пор дка 10%), отража сь от пластинки 5, проходит через дополнительный объектив и, отража сь зеркалом 9, создает изображение на контрольном экране 10.The luminous flux coming out of the lens 4 and falling on the plane-parallel plate J, it is divided by two Macjii. Most of the light current (QO / fc) passes through the plate 5 and is rejected by the mirror 6 on the working screen 7; a smaller part (on the order of 10%), reflected from plate 5, passes through an additional lens and, reflected by mirror 9, creates an image on the control screen 10.
