摘要： A compact rolling loop motion picture projector has a rotor of significantly smaller diameter than a conventional such rotor. The radius of curvature of the rotor is selected to be significantly less than the radius of curvature of a film flattener element on which the film is located for projection, and the axis of rotation of the rotor is offset towards a film input sprocket of the projector so as to maintain a minimum film gap between the rotor and the field flattener upstream of the optical axis of the projector. The compact rotor is rotationally supported from above by a "spider" and a projection lamp is located below the rotor for compactness and efficiency of lamp operation.

摘要： A rolling loop motion picture projector is convertible for projecting images either from a 2-D film strip or from a 3-D film strip. The film is advanced through the same incremental amount irrespective of whether a 2-D film of a 3-D film is being projected. The projector has a single central aperture for projecting 2-D images and respective 3-D images on opposite sides of the central aperture. The images on the 3-D film strip are anamorphically compressed in the direction of film travel by a factor of two and the 3-D apertures are correspondingly sized. Projection lenses associated with the 3-D apertures decompress the images so that images of comparable size appear on the screen irrespective of whether a 2-D film or a 3-D film is being shown.

摘要： An electronic projector has a projection system that includes a spatial light modulator (SLM) for importing image information to the projected light beam. The light beam leaving the SLM is prepolarized in a defined orientation and the projected light is polarized in the same orientation so as to effectively block any light that has been scattered within the projector and become depolarized. The SLM may be a digital mirror device (DMD). Reflective surfaces within the projector may be covered or coated with material that alters the polarization of reflected stray light from the defined orientation or depolarizes the reflected stray light.

摘要： A xenon arc lamp for a motion picture projector is cooled by providing the anode end of the lamp with a shroud that forms part of a support for that end of the lamp. Cooling air flows into the shroud along the support arm and enters the shroud through a slot in its side wall. The shroud provides an annular air space around the anode end of the lamp and has an annular air outlet through which the cooling air leaves as a “sheet” of laminar air flow which tends to adhere to the surface of the bulb, thereby providing precise cooling. In this way, arc instability is avoided or minimized, while lamp life is extended.
摘要翻译：用于电影投影仪的氙弧灯通过为灯的阳极端提供形成用于灯的该端部的支撑件的一部分的护罩来冷却。冷却空气沿着支撑臂流入护罩并通过其侧壁中的槽进入护罩。护罩在灯的阳极端附近提供环形空气空间，并且具有环形空气出口，冷却空气通过该环形空气出口作为层流气流的“片材”离开，倾向于粘附到灯泡的表面，从而提供精确的冷却。以这种方式，避免或最小化电弧不稳定性，同时延长灯的寿命。
