Abstract: In described examples, a method of creating multiple light images uses spatially-separated light sources, arranged in an array, operated in multiplexed fashion, for driving a spatial light modulator. Each of the light sources is time-sequenced to direct light at the spatial light modulator during a time interval. The spatial light modulator is synchronized with the light sources and controlled to produce a desired image during each time interval. The resulting images are received by an optical lens system to provide light images along an image plane. Alternately, the optical lens system focuses the modulated light images on a hogel plane to produce a light field. The pixel count of the spatial light modulator is effectively multiplied by the number of light sources.

Abstract: A system having a color filter having first and second segments. The first and second segments allow respective first and second wavelengths to pass through to a spatial light modulator. The first and second segments also reflect second and first wavelengths, respectively. The reflected first and second wavelengths are recycled and directed towards the color filter.

Abstract: In described examples, a method of creating multiple light images uses spatially-separated light sources, arranged in an array, operated in multiplexed fashion, for driving a spatial light modulator. Each of the light sources is time-sequenced to direct light at the spatial light modulator during a predetermined time interval. The spatial light modulator is synchronized with the light sources and controlled to produce a desired image during each time interval. The resulting images are received by an optical lens system to provide light images along an image plane. Alternately, the optical lens system focuses the modulated light images on a hogel plane to produce a light field. The pixel count of the spatial light modulator is effectively multiplied by the number of light sources. Each light source may sequentially provide multiple colors to produce a full-color image. The light source array may, in turn, be driven by one or more remotely-located master light sources.
Abstract translation: 在所述示例中，创建多个光图像的方法使用空间分离的光源，以阵列方式布置，以多路复用方式操作，用于驱动空间光调制器。 在预定时间间隔期间，每个光源被时间序列化以在空间光调制器处引导光。 空间光调制器与光源同步并被控制以在每个时间间隔期间产生期望的图像。 所得到的图像由光学透镜系统接收以提供沿着图像平面的光图像。 或者，光学透镜系统将调制的光图像聚焦在光栅平面上以产生光场。 空间光调制器的像素数乘以光源的数量。 每个光源可以顺序地提供多种颜色以产生全色图像。 光源阵列又可以由一个或多个位于远程的主光源驱动。

Abstract: In described examples, a digital light processing color projector includes light emitters configured to collectively emit light at multiple wavelengths, multiple light directing elements forming an illumination path having at least one aperture stop, a micromirror array coupled to a substrate, an aperture located at the aperture stop, and a filter with a selected color transmittance profile located at or near the aperture stop. The light directing elements are configured to direct light towards the micromirror array as illumination light. An aperture width determines a diameter of the illumination light. A micromirror on-state reflects the illumination light as on-state light. The substrate reflects the illumination light as flat-state light. The light directing elements direct on-state light through the aperture to a projector output. The filter filters flat-state light in an overlap region of the on-state light and flat-state light, or an illumination light portion corresponding to overlap region.

Abstract: An image may be formed in a projection system by forming a light beam with substantially a first polarization. The light beam is directed onto a first color wheel that transmits a first selected color portion of the light beam and reflects a second color portion of the light beam. The reflected second color portion is converted to a second polarization. A first portion of the image is produced with a first spatial light modulator using the first selected color portion of the light beam having the first polarization. A second portion of the image is produced with a second spatial light modulator using at least a portion of the reflected second color portion of the light beam having the second polarization. The first portion of the image and the second portion of the image are combined to form a combined image for projection.

Abstract: Apparatus and methods are disclosed for generating blue color illumination for use in a projection system. Light from a blue laser light source is reflected off a dichroic filter sequentially onto different color emitting phosphor coated light non-transmissive segments and onto a cyan color emitting phosphor coated light transmissive segment of a rotating color wheel. The different color light and cyan color light emitted by the phosphor back to the filter is selectively transmitted by the filter along a projection path. Blue laser light and cyan color light emitted by the phosphor transmitted through the color wheel is directed along a wraparound optical path back to the filter for reflection along the projection optical path.

A first portion of the image is produced with a first spatial light modulator using the first selected color portion of the light beam having the first polarization. A second portion of the image is produced with a second spatial light modulator using at least a portion of the reflected second color portion of the light beam having the second polarization. The first portion of the image and the second portion of the image are combined to form a combined image for projection.
