摘要： The present disclosure relates generally to an optical element, a light projector that includes the optical element, and an image projector that includes the optical element. In particular, the optical element provides an improved uniformity of light by homogenizing the light with lenslet arrays, such as “fly-eye arrays” (FEA). A first FEA is positioned to intercept and converge an unpolarized combined light before the light is converted to a single polarization state, and a second FEA is positioned to intercept and diverge the converted light having a single polarization state.

摘要： A light source combines colored light from different LED sources to provide white light output. Multiple LEDs emitting light at different peak wavelengths may be disposed on a flexible substrate, the LEDs being close to an aperture formed in the substrate. Multiple mirrors, including at least one dichroic mirror, are oriented to reflect light from the multiple LEDs into the aperture. The flexible substrate includes a dielectric layer having a cavity region and an adjacent neighboring region that is thicker than the cavity region. The aperture and the multiple LEDs are all disposed in the cavity region of the dielectric layer. An integrating rod may be coupled to the aperture to receive the reflected light from the multiple LEDs.

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. In one aspect, the received light inputs are unpolarized, and the combined light output is also unpolarized. The optical elements can be 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： Generally, the present disclosure describes a compact optical integrator that provides an increased path length for a beam of light in a compact projection system. The increased path length can improve the uniformity of the light passing through the compact projection system, with a minimal increase in the size of the system. The light can be homogenized by mixing light entering the integrator from different regions of the input area. The compact optical integrator can be positioned in the optical path between a light source and a spatial light modulator, such as a liquid crystal display (LCD) or a digital micro-mirror (DMM) array.
