摘要： A miniature imager for reading target images. The optical and electrical systems of the miniature imager are optimized to reduce one or more dimensions or the volume of the imager. In accordance with one embodiment the pixel pitch and focal length are decreased for that of a larger imager to maintain a comparable field of view for each pixel. The decreased pixel pitch allows the area of the aperture and the instantaneous field of view of the pixel to remain constant while decreasing the overall size of the imager. In other embodiments apparatus and techniques reduce and/or eliminate the need for illumination of a target by the imager thereby reducing the overall power consumed by the imager and/or its overall size. The imager has an increased working range.
