    • A see-through head mounted display apparatus with reduced eyeglow is disclosed. Two images of a scene are combined and presented to a user, the combined image including portions of reflected image light and light from a see-through view of an external environment. The apparatus includes a light control element to block escaping portions of image light and reflected portions of scene light, while allowing incoming scene light to be transmitted from the external environment. The images are produced using a partially reflecting mirror and a light control element. A portion of scene light is transmitted through the partially reflecting mirror and is combined with a portion of image light reflected from the partially reflecting mirror. A light control element is used to block a portion of the image light and a portion of the scene light to reduce eyeglow.

    • A tissue imaging system (200) for examining the medical condition of tissue (290) has an illumination optical system (205), which comprises a light source (220), having one or more light emitters, beam shaping optics, and polarizing optics. An optical beamsplitter (260) directs illumination light to an imaging sub-system, containing a spatial light modulator array (300). An objective lens (325) images illumination light from the spatial light modulator array to the tissue. An optical detection system (210) images the spatial light modulator to an optical detector array. A controller (360) drives the spatial light modulator to provide time variable arrangements of on-state pixels. The objective lens operates in a nominally telecentric manner relative to both the spatial light modulator and the tissue. The polarizing optics are independently and iteratively rotated to define variable polarization states relative to the tissue. The modulator pixels optically function like pinholes relative to the illumination light and the image light.
    • 用于检查组织(290)的医学状况的组织成像系统(200)具有照明光学系统(205),其包括具有一个或多个光发射器,光束整形光学器件和偏振光学器件的光源(220)。 光分束器(260)将照明光引导到包含空间光调制器阵列(300)的成像子系统。 物镜(325)将来自空间光调制器阵列的照明光图像转印到组织。 光学检测系统(210)将空间光调制器成像到光学检测器阵列。 控制器(360)驱动空间光调制器以提供导通状态像素的时间可变布置。 物镜相对于空间光调制器和组织以标称远心方式工作。 偏振光学器件被独立地并且迭代地旋转以限定相对于组织的可变极化状态。 调制器像素相对于照明光和图像光光学地起着像针孔的作用。
