    • Disclosed are a system and method for microprojection that uses multiple imagers to produce a high resolution output image. Each of a set of imagers produces a portion of the final image. Relay lenses then tile the individual image portions together into a combined image. Because the height of the individual imagers is smaller than the height of a monolithic imager, they can fit into a very thin device. The combined image has a resolution equal to the sum of the resolutions of the individual imagers. The individual images are tiled together within the microprojector itself rather than on a projection screen. This allows the tiling to be adjusted once at the factory and set forever. In some embodiments, the light created for use by the microprojector is split by a polarizing beamsplitter. Each resultant polarized beam is then sent to an imager. Another polarizing beamsplitter combines the individual images.
    • 公开了一种用于微喷射的系统和方法,其使用多个成像器来产生高分辨率输出图像。 一组成像器中的每一个产生最终图像的一部分。 然后,中继透镜将各个图像部分拼接成合成图像。 因为单个成像器的高度小于单片成像器的高度,所以它们可以适合于非常薄的器件。 组合图像的分辨率等于各个成像器的分辨率的总和。 各个图像在微型投影仪本身内平铺在一起,而不是在投影屏幕上。 这样就可以在工厂进行一次调整,并永久设定。 在一些实施例中,由微型喷射器使用而产生的光被偏振分束器分开。 然后将每个合成的偏振光束发送到成像器。 另一个偏振分光镜组合了各个图像。

    • Disclosed are a system and method for microprojection that uses a “reduced-height” imager to sequentially display a series of partial images within one frame time. The partial images visually combine on a projection surface (e.g., a screen or a wall) into one high-resolution projected image. As a result, the microprojector projects an image with a resolution equal to the sum of the resolutions of the individual partial images while avoiding the use of very small imager optics with their lowered efficiency. For example, one embodiment projects exactly two partial images during each frame. During a first state of operation, a “half-height” imager displays the odd-numbered lines of the projected image. During a second state of operation, the imager displays the even-numbered lines of the projected image. By quickly cycling through these two states, no image flickering between phases is visible, and the combined image appears as a seamless whole.
    • 公开了一种使用“降低高度”成像器在一帧时间内顺序显示一系列部分图像的微喷射系统和方法。 部分图像在投影表面(例如,屏幕或墙壁)上可视地组合成一个高分辨率投影图像。 结果,微型投影仪以等于各个部分图像的分辨率的总和的分辨率来投影图像,同时避免使用非常小的成像器光学器件,其效率降低。 例如,一个实施例在每个帧期间准确地投影两个部分图像。 在第一操作状态下,“半高”成像器显示投影图像的奇数行。 在第二种操作状态下,成像器显示投影图像的偶数行。 通过快速循环通过这两个状​​态,阶段之间没有可见的图像闪烁,并且组合的图像显示为无缝整体。
