    Abstract: A baffle assembly directing air flow for cooling electrical components by providing three-dimensional separation of the air flow for individual cooling air streams. The assembly includes a first baffle portion composed of a conduit of material and a second baffle portion composed of a sheet of material and coupled to the first baffle portion. The first baffle portion directs a first portion of the air flow to a first electrical component for cooling the first electrical component and directs a second portion of the air flow around the first electrical component to maintain a cool air stream. The second baffle portion directs the first portion of the air flow around a second electrical component as waste heat and directs the second portion of the air flow to the second electrical component for cooling the second electrical component.

    Abstract: A folded light path illuminator is provided. The illuminator may include a polarizing beam splitter having an input face, an output face and an imager face, a light source disposed adjacent the input face and defining an input active area on the input face, and an image forming device disposed adjacent the imager face for receiving light emitted from the light source and emitting a patterned light, which may be a converging patterned light. The image forming device may have a largest image area which defines an output active area on the output face. One or both of the input active area and the output active area may be less than about half the largest image area. The polarizing beam splitter may include first and second prisms and the volume of the first prism may be no greater than half the volume of the second prism.

    Abstract: An image combiner, also referred to as a combiner optic, of a near-eye display system or the like transmits enough light so a user can see remote objects in a "world view", while also reflecting enough light so the user can simultaneously see a projected image in a "projected" (augmented) view. The disclosed image combiners use two partial reflectors configured to form a wedged reflective cavity. In the display system, light from an imaging device follows a path to the user's eye that includes three reflections in the wedged cavity. By using this capability of the wedged cavity, the combiner optic can have a substantially reduced thickness, and lower profile, than a combiner optic that uses only one partial reflector and only one reflection in the optical path.

    Abstract: Projection systems and components thereof are described that are well suited to miniaturization. These systems and components may use one or more of the following features: a folded optical path, as in a reflective cavity or a beamsplitter; an illumination beam that is converging at the place where it impinges upon the spatial light modulator; a beamsplitter that uses opposed prisms of substantially different sizes; a beamsplitter whose obliquely disposed partial reflector defines a first rectangular reference space, and where at least a portion of the light source or at least a portion of the projector lens is disposed within such first rectangular reference space; a system in which a ratio of areas of the first rectangular reference space and a second rectangular reference space is within a specified range, where the second rectangular reference space is just large enough to encompass the optical components of the projector; a system in which the projector lens is small compared to the spatial light modulator.
