METHOD OF OPTICALLY ANALYSING IMAGE IN BACK-PROJECTION SCREENS AND PROJECTION SCREEN THEREFOR

摘要

The essence of the invention in range of the method, mainly consists in the fact that: the light image generated by the projector is projected on the rear surface of the screen, optical analysis takes place on its fore surface through transparent optical microelements due to which a contrastive image without a glare effect is obtained on the fore surface of the screen. However, as far as the screen structure is concerned, the essence of the invention consists in the fact that: to make an optical analysis of the image with rear projection the screen is made in the form of the panel made of transparent material of the structure which enables to obtain a contrastive image on the fore surface without a glare effect, and that in the panel of the screen (1) there are embedded optical microelements (2).
