    • A theater utilizes multiple projectors that are widely spaced. The wide spacing of the projectors reduces hot spotting that occurs on flat, curved, retro-reflective, and other types of screens. The projectors are spaced widely apart and generally are placed at opposite sides of the theater. The wide spacing causes a trapezoidal distortion or effect which may be electronically compensated for by, for example, changing pixel locations on modulators of the projectors such that same (or corresponding) pixels modulated in both projectors are ultimately projected onto a same pixel area of the screen. The invention is particularly advantageous in polarization based 3D systems which generally require high directivity screens where hot spotting and related crosstalk are common.
    • 剧院使用了广泛间隔的多台投影机。 投影机的宽间距减少了在平面,弯曲,反光和其他类型屏幕上发生的热点。 投影机间隔很远,通常放置在剧院的相对两侧。 宽间距引起梯形失真或效应,其可以通过例如改变投影仪的调制器上的像素位置进行电子补偿,使得在两个投影仪中调制的相同(或对应的)像素最终投影到相同的像素区域上 屏幕。 本发明在基于偏振的3D系统中是特别有利的,其通常需要高指向性屏幕,其中热点和相关的串扰是常见的。

    • Several embodiments of projection systems are disclosed that comprise a plurality of controllable emitters, each said emitter providing light for a light path; a plurality of first optical elements, each said first optical element receiving light from one of said emitters; a controllable modulator receiving light from said plurality of first optical elements; a plurality of conduits, each said conduit disposed over a portion of said controllable modulator; a plurality of second optical elements, each of said second optical elements receiving light from at least one of said plurality of conduits, and a controller for sending control signals to said controllable emitters and said controllable modulator. The illumination from the emitters may form a plurality of overlapping areas of illumination upon a projection screen where the image is intended to be formed.
