MATRIX SCREEN |
摘要 |
FIELD: information technology, design of large-scale screens for collective usage from set of individual screens of smaller dimensions. SUBSTANCE: matrix screen incorporates set of image elements on which surfaces device with interelement gaps for image correction is located. This device is made in the form of flat objective composed of two Fresnel lenses separated by transparent coupling medium. Function of optical scaling is realized due to profiles of lenses, selection of lens materials and coupling medium which refractive indices are different. EFFECT: exclusion of zone of distorted image. 2 cl, 1 dwgc
