摘要： Optical elements, color combiners using the optical elements, and image projectors using the color combiners are described. The optical elements can be configured as color combiners that receive different wavelength spectrums of light and produce a combined light output that includes the different wavelength spectrums of light. In one aspect, the received light inputs are unpolarized, and the combined light output is polarized in a desired state. The optical elements are configured to minimize the passage of light which may be damaging to wavelength-sensitive components in the light combiner. Image projectors using the color combiners can include imaging modules that operate by reflecting or transmitting polarized light.

摘要： Light combiners and light splitters, and methods of using light combiners and light splitters are described. In particular, the description relates to light combiners and splitters that combine and split, respectively, light of different wavelength spectrums using polarizing beam splitters. The polarizing beam splitters include a reflective polarizer to efficiently split incident light into transmitted and reflected beams having different polarization directions. Reflectors and quarter-wave retarders are positioned facing selected prism faces of the polarizing beam splitters, to affect the polarization state of light passing through the prism faces. The reflectors can be dichroic filters adapted to reflect light that is outside a selected wavelength range, so that light of different wavelength spectrums can be affected at different prism faces. The surfaces of each polarizing beam splitter can be polished so that the light utilization efficiency is increased due to total internal reflection within the polarizing beam splitter. The light combiners can combine up to five unpolarized different color lights to produce an unpolarized polychromatic light output, which may be white light useful for a projection display. The light splitters can split unpolarized polychromatic light to produce up to five unpolarized different color light outputs.

摘要： A projection system includes a projection lens unit, a color combiner, and at least a first and a second image-forming devices for generating single color images. The single color images are combined in the color combiner to produce a colored image light beam. The colored image light beam passes from the color combiner to the projection lens system. A polarization control element is disposed between the color combiner and the first image-forming device. The polarization control element alters the polarization of light at either one of the first and second color, while not altering the polarization of light of the other of the first and second color. In some embodiments, the polarization control element is oriented to substantially prevent light at the second color from passing from the color combiner to the first image-forming device via a polarizing beamsplitter.

摘要： Single imager projection systems suffer from low light throughput, compared to three imager systems, because only one color band is illuminated at any one time. As a result, there is a need to increase the operating efficiency of the single imager projection system. The invention is directed to the incorporation of a high extinction ratio pre-polarizer, such as a compensated, multi-layer polarizer, in a single or dual imager projection system. This permits illumination with low f-number illumination light, and thus increases the efficiency of the projection system. The pre-polarizer may be incorporated within a polarization recovery unit to further enhance system efficiency.

摘要： An optical system and a projection system incorporating same are disclosed. The optical system includes first and second optical elements. The second optical element is polarization insensitive in the visible. The first optical element is capable of receiving light of a first polarization along a first direction and transmitting the received light along the first direction. The first optical element is also capable of receiving light of a second polarization orthogonal to the first polarization along the first direction and reflecting the received light along a second direction different from the first direction. When the optical system receives light of the first polarization along the second direction, the first optical element transmits the received light along the second direction. The transmitted light has the first polarization and a first set of color coordinates. The second optical element transmits at least a portion of the light transmitted by the first optical element. The light transmitted by the second optical element has a second set of color coordinates that is different from the first set of color coordinates.

摘要： A compound polarization beam splitter (33) for use with a reflective, polarization-modulating, imaging device (10), e.g., a LCoS device, is provided. The compound PBS has: (a) an input prism (20); (b) an output prism (30), and (c) a polarizer (13), which is located between the two prisms (20,30) and which may be a wire grid polarizer (13a) or a multi-layer reflective polarizer (13b). Polarized illumination light (11) enters the input prism (20) through a first surface (21) and undergoes total internal reflection at a second surface (22) before being reflected from the polarizer (13) and polarization-modulated at the imaging device (10). The polarizer's tilt angle (&bgr;) is less than 45°, which reduces astigmatism and the required back working distance of the system's projection lens (74).

The steps include measuring a first light intensity, LR, in the folded light path, having a first polarizing beam splitter, and a reflective display.
