    • An electro-optical imaging array having pixels arranged in rows and columns electronically compensates for image motion in the plane of the array regardless of whether the motion vector is in the row direction, the column direction, or in a diagonal direction, i.e., in some vector combination of row and column directions. In an aerial reconnaissance application, the image motion may be due to rotation of the aircraft about roll, pitch and/or yaw angles in addition to forward velocity of the aircraft. The image motion compensation is achieved with no moving parts and does not require a stabilized platform. A camera control computer determines the magnitude and direction of the image motion from inertial navigation system inputs, including velocity, flight, and aircraft rotation information, and calculates pixel information transfer rates in the row and column directions. The pixel information transfer rates are supplied to a counter and clock driver circuit for the array. The pixel information in the array is transferred in the row and column direction in a step-wise fashion in the row and column directions at a rate and direction substantially matching the image motion. The array itself is provided with a gate and control line design to enable charge representing pixel information to be transferred in both the row and column directions.
    • 具有排列成行和列的像素的电光学成像阵列电子地补偿阵列的平面中的图像运动,而不管运动矢量是在行方向,列方向还是在对角线方向上,即在某些方面 行和列方向的向量组合。 在空中侦察应用中,图像运动可能是由于除了飞行器的向前速度之外,飞机关于滚动,俯仰和/或偏航角度的旋转。 图像运动补偿无需移动部件即可实现,不需要稳定的平台。 相机控制计算机确定惯性导航系统输入的图像运动的大小和方向,包括速度,飞行和飞行器旋转信息,并计算行和列方向上的像素信息传输速率。 像素信息传送速率被提供给阵列的计数器和时钟驱动器电路。 阵列中的像素信息在行和列方向上以逐行方式以基本上与图像运动匹配的速率和方向在行和列方向上传送。 阵列本身设置有栅极和控制线设计,以使得能够在行和列方向上传送代表像素信息的电荷。

    • A two-dimensional focal plane array (FPA) is divided into sub-arrays of rows and columns of pixels, each sub-array being responsive to light energy from a target object which has been separated by a spectral filter or other spectrum dividing element into a predetermined number of spectral bands. There is preferably one sub-array on the FPA for each predetermined spectral band. Each sub-array has its own read out channel to allow parallel and simultaneous readout of all sub-arrays of the array. The scene is scanned onto the array for simultaneous imaging of the terrain in many spectral bands. Time Delay and Integrate (TDI) techniques are used as a clocking mechanism within the sub-arrays to increase the signal to noise ratio (SNR) of the detected image. Additionally, the TDI length (i.e., number of rows of integration during the exposure) within each sub-array is adjustable to optimize and normalize the response of the photosensitive substrate to each spectral band. The array provides for parallel and simultaneous readout of each sub-array to increase the collection rate of the spectral imagery. All of these features serve to provide a substantial improvement in the area coverage of a hyperspectral imaging system while at the same time increasing the SNR of the detected spectral image.
    • 二维焦平面阵列(FPA)被划分为行和列的像素的子阵列,每个子阵列响应于已经被光谱滤波器或其他频谱分割元件分离的目标对象的光能 预定数量的光谱带。 对于每个预定的光谱带,FPA上最好有一个子阵列。 每个子阵列都有自己的读出通道,以允许并行和同时读出阵列的所有子阵列。 将场景扫描到阵列上,以便在许多光谱带中同时成像地形。 时间延迟和积分(TDI)技术被用作子阵列内的时钟机制,以增加检测到的图像的信噪比(SNR)。 此外,每个子阵列内的TDI长度(即,曝光期间的积分行数)是可调整的,以使感光基片对每个光谱带的响应进行优化和归一化。 该阵列提供并行和同时读取每个子阵列以增加光谱图像的采集速率。 所有这些特征用于提供高光谱成像系统的面积覆盖的显着改进,同时增加检测到的光谱图像的SNR。

    • Tapping apparatus for tapping holes in workpieces is provided with a tap assembly that includes a tap fitted to a lower tip end of a vertical lead screw, there being means including a bushing for rotating the lead screw thereby to vertically advance and retract the tap relative to the a workpiece hole. Power operating means are provided to rapidly advance and retract the lead screw independently of rotating advance/retraction of the lead screw so as to more quickly locate the tap proximal the workpiece hole allowing that tapping commences with lessened need for lead screw rotation as a means of effecting lineal advance of the lead screw. This lessens the tapping cycle time and results in increased production rate with the apparatus as well as lengthening tap life. The power operating means also functions to rapidly retract the lead screw and tap upwardly from the workpiece on completion of the tapping which also increases production particularly where the workpiece includes heightened structure adjacent the hole location so that more rapid tool clearance is achieved permitting quicker workpiece indexing to present a next to be tapped hole at a tapping station.
