    • Diffuse “dark field” illumination and “bright field” illumination are each provided for a hand-held encoded symbology imager/reader; to be projected therefrom upon symbology disposed on a target (component part, goods, package, etc.). The imager/reader is encased in a housing ergonomically configured to be griped in more then one manner and to thus facilitate holding the imager/reader steady. The symbology to be imaged is targeted by a line that not only spots the symbology, but by extending a length commensurate with that of the symbology, indicates that the symbology is in the field of view of the imager/reader. A CCD, disposed to receive light reflected from the symbology, has its readout controlled so that only selected portions of the CCD need be analyzed for illumination and focusing purposes. To optimize imaging and decoding time, and to optimize use of power, readout from some portions of the CCD is accomplished in relatively rapid time by speeding up the readout of the CCD in some of its active area; while reverting back to a slower readout for data to be analyzed for illumination and focusing control and decoding purposes. In addition, special application of entropy principles facilitate determining the optimum focus and illumination conditions for the imager/reader.
    • 漫射“暗场”照明和“亮场”照明分别为手持编码的符号系统成像仪/阅读器提供; 从配置在目标上的符号系统(部件,商品,包装等)投射出来。 成像器/读取器被封装在符合人体工程学的外壳中,以便以一种方式被夹持,从而有利于保持成像器/读取器的稳定。 要成像的符号系统的目标是一条线,不仅可以识别符号系统,而且通过扩展与符号系统相匹配的长度,表示符号系统在成像器/读取器的视野中。 设置为接收从符号系统反射的光的CCD具有其读出控制,使得仅需要分析CCD的所选部分以进行照明和聚焦。 为了优化成像和解码时间,并且优化功率的使用,通过在其一些有效区域中加速CCD的读出,在相对较快的时间内从CCD的一些部分读出; 同时还原为较慢的读数,以供分析用于照明和聚焦控制和解码目的的数据。 此外,熵原理的特殊应用有助于确定成像器/读取器的最佳聚焦和照明条件。

    • A stereoscopic objective lens system for video endoscopes and borescopes includes two full-diameter doublets and two lens pairs forming a stereo lens set. A rotatable dual telescope is disposed between the two doublets and the stereo lens pairs, establishing a Galilean telescope associated with each stereo channel. The Galilean telescopes are each rotatable, preferably in convert, to be in or out of alignment with the system optical axis. When out of alignment, the Galilean telescopes have no effect along the optical path. When in alignment, the Galilean telescopes provide an increase or decrease in magnification, depending on orientation of the telescopes. The full-diameter doublets present equal-angle pairs from symmetrically disposed object points to the lenses of the stereo lens pair. This equal-angle property enables accurate object/image mapping onto the final stereo image pair, such that all parts of each left/right image can be mapped to within a fraction of a video pixel to each other.
    • 用于视频内窥镜和内窥镜的立体物镜系统包括形成立体镜组的两个全直径双重透镜和两个透镜对。 可旋转的双重望远镜设置在两个双重透镜和立体镜对之间,建立与每个立体声通道相关联的伽利略望远镜。 伽利略望远镜各自可旋转,优选地转换成与系统光轴对准或不与其对准。 不对准时,伽利略望远镜沿光路无效果。 当对准时,伽利略望远镜根据望远镜的方向提供放大倍率的增加或减小。 全直径双层具有从对称设置的对象点到立体镜对的透镜的等角对。 该等角属性使得能够在最终的立体图像对上进行准确的对象/图像映射,使得每个左/右图像的所有部分可以被映射到彼此的视频像素的一小部分内。

    • An endoscope relay lens is disclosed for transmitting an optical image along a narrow cylinder. Relay lenses are typically utilized in pairs to constitute a relay lens set and one or more sets are utilized in medical endoscopes. In the preferred embodiment, the relay lens includes two identical end lenses affixed to opposed ends of a center lens to define a cylinder. The relay lens is symmetrical about a plane bisecting the center of the center lens. The axial length of each end lens is equal to or greater than one-half its diameter. Optimal performance characteristics are achieved when the radii of curvature of the lenses and the axial lengths of the lenses cooperate so that the distance from an object being viewed to the exterior surface of the end lens closest to the object is one-half the distance between relay lenses in a pair and one-half the distance between sets of relay lens pairs. In one embodiment the center lens is spherical.
