Large-format projection - a brief history
Large format projection was originally developed by Ludwig Pani in Austria for use in theatre and opera. Some time later, French company ETC Audiovisuel expanded the capabilities of large format projection by developing an accurate film scroller that allowed for basic scrolling animation of film transparencies opening the door to large scale multiple projector panoramas. Before long ETC began making their own projectors using a Xenon light source because of its increased efficiency when used with long distance lenses. Eventually the PIGI system evolved to its current form using double film scrollers mounted on a rotational turret. Modern robotic techniques are employed in order to achieve the extreme film movement and positioning accuracy required for large projector arrays.
The PIGI system uses film transparencies that yield beautiful continuous tone high resolution images.
Using a 6kw Xenon light source the PIGI projector is capable of upwards of 80,000 lumens of light output making them by far the most efficient and cost effective choice for covering large areas.
PIGI is a french acronym that translates as "Giant Image Projector with Computer Control"
