    Abstract: An optical scanner device for producing machine-readable data representative of an image of a scan line object, comprising: a light source for illuminating the scan line object; a lens assembly for focusing imaging light received from the scan line object on an image plane; at least one mirror having a planar mirror surface for reflectively directing imaging light from the scan line object into the lens assembly whereby a folded imaging light path extending between the scan line object and the lens assembly is provided; and an occluding aperture stop positioned in immediately adjacent, overlying relationship with the mirror surface for selectively differentially blocking light in the light path emanating from different points across the scan line object for adjusting the light intensity of the image produced on the image plane whereby blocking of light with the occluding aperture stop at more than one location along the folded imaging light path is obviated. Alternative embodiments utilizing a gradient filter and a shaped mirror surface are also disclosed.

    Abstract: An electro-optical imaging system uses a charge-coupled bucket-brigade photo-sensitive image convertor where the necessity for light shielded shift registers and other measures for preventing the acquisition of additional incident-light induced charge by light-representative electrical charge packets as they pass to the output port of the convertor is removed by the use of a liquid crystal light transmission cell which can be made transparent for the acquisition of charge by the convertor and opaque for the shifting of the charges to the output port. The convertor can thus be made simpler and of smaller area to give a lower cost and higher production yield. The convertor is given an apparently increased spatial resolution by providing that the cell allows sub-areas of the total image to be transmitted one-by-one to the convertor by the sequential operation of four sub-cells of the main cell such that each sub-cell becomes transparent and has its through-passing image converted in turn.

    Abstract translation: 电光成像系统使用电荷耦合的桶式光敏图像转换器，其中需要光屏蔽移位寄存器和其他措施，以防止通过光代表性电荷包收集额外的入射光感应电荷，因为它们 通过使用液晶透光单元去除转换器的输出端口，该液晶透光单元可以变得透明，以便由转换器获取电荷并且不透明以将电荷转移到输出端口。 因此，转换器可以变得更简单和面积更小，从而降低成本和更高的产量。 通过提供单元允许总图像的子区域通过主单元的四个子单元的顺序操作一个接一个地向转换器传送，使转换器具有明显增加的空间分辨率，使得每个子 -cell变得透明并且依次转换其通过图像。

    Abstract: A raster input scanner (RIS) comprising a platen and light source, doubling mirror, lens and two CCD arrays for producing a bit stream output with twice the resolution produceable with a single CCD is disclosed. The doubling mirror is between the platen and lens, and produces two beams separated by a small angle. The lens focuses these beams as two lines at the image plane, where half of each intersects each CCD array. Glass plates, each intersecting and perpendicular to each beam, and rotatable about orthogonal axes, provide horizontal and vertical fine tuning.

    Abstract: Selected embodiments use a relatively small image detector and a scanning mirror to obtain effective performance of a larger image detector. An imager with folded optics captures images of different field positions of a field of view (FOV), and stitches the images together for a larger image of the FOV. The stitched image is processed to identify portions of interest within the larger image, for example, using a cuing algorithm. The portions of interest are scanned again to capture enhanced quality images using, for example, longer dwell time for enhanced contrast. Another image of the FOV or a part of the FOV is stitched together using the enhanced quality images.
