A viewing apparatus (,) for transparencies or the like masks any display areas (,) not covered by transparencies (,) by generating masks without moving parts, and adapts the luminance level of the image under study and of other display areas to the optimal viewing conditions required by the observer.

Self-masking transparency viewing apparatus

A method for viewing transparencies comprising backlighting a transparency with polarized light and viewing the transparency through a polarizer. Preferably, the polarization axis of the backlighting and the polarization axis of the polarizer are oriented at about 90 degrees to each other. The transparency is oriented so that a substantial amount of polarized backlighting passes through the transparency and the polarizer. Also disclosed are apparatus for viewing a transparency using polarized backlighting.

Automatic transparency masking

Viewing apparatus including a viewing surface having a viewing area, back-lighting apparatus for selectably adjusting the back-illumination of areas of the viewing surface, the areas having a given extent, the back-lighting apparatus including: a liquid crystal array of individually controllable liquid crystal light attenuators located behind the viewing surface, each element of the array being associated with an area of the viewing surface and including active elements having a controllable opacity over an area smaller than the given extent of the area with which it is associated, and inactive areas between the active elements, a light source behind the array of light attenuators and a plurality of light guides, each associated with an element of the array and located between the element and its associated area on the viewing surface for providing controlled illumination of the associated area including at least a portion of the space surrounding the active element.
