摘要： A current-driven load such as LEDs or laser diodes is driven by a current driver having a two stages (or phases), the outputs of which have ripple which is forced to be out-of-phase with one another. In analog embodiments, an output (ripple or switching) of a master stage hysteresis controller is phase-shifted and scaled, and modulates the input of a slave stage hysteresis controller so that the slave stage pulls into a ripple-canceling phase. In digital embodiments, a faster of the two phases is designated “master”, maximum and minimum thresholds are set, and the slave phase's on time is based on a previous cycle's slave phase ON time, the master stage OFF time and an offset. The slave controller may “lock” to the anti-phase of the master stage (or phase). The ripple currents at the summed output of the master and slave stages substantially cancel.

摘要： A laser spot tracker comprising a quadrant detector. A portion of a spot of laser light reflected from an object being illuminated (OBI) may be defocused to occupy a significant portion such as one-third of the field of view, while another portion remains focused, therefore allowing for quick calculation of the spot centroid. With such a “composite spot”, multiple target (OBI) positions may simultaneously be defined in elevation and azimuth with respect to null by analyzing the energy in each quadrant. The X and Y angle information (off null) for multiple targets (OBIs), and their codes may be displayed. For a large, defocused spot, two segmented multi-element detectors may be used, one in front of and the other behind the focal plane to reduce the effects of hot spots in a spot of laser light collected from an object being illuminated.
摘要翻译：包括象限检测器的激光点跟踪器。从被照明物体（OBI）反射的激光光斑的一部分可以散焦以占据诸如视场三分之一的重要部分，而另一部分保持聚焦，因此允许快速计算斑点重心。通过这样的“复合点”，通过分析每个象限中的能量，可以同时在高程和方位上定义多个目标（OBI）位置相对于零。可以显示多个目标（OBI）的X和Y角度信息（关闭空值）及其代码。对于大的散焦点，可以使用两个分段多元件检测器，一个在焦平面之前，另一个在焦平面之后，以减少从被照射物体收集的激光光斑中的热点的影响。

摘要： A laser spot tracker device comprising a laser tracker receiver using a quadrant detector incorporated into a pair of binoculars or optical telescope system with a crosshair or reticule. Directional information from the laser tracker receiver is displayed to an operator (JTAC) to allow the reticule to be manually steered on to the target illuminated by the laser, thus identifying the target to the spotter. The laser code may be pre-selected to track a particular designator, or, the tracker may read out the code or codes of laser spots within its field of view.
摘要翻译：一种激光瞄准器装置，其包括使用结合到一对双目镜中的象限检测器的激光跟踪器接收器或具有十字准线或网状的光学望远镜系统。来自激光跟踪器接收器的定向信息被显示给操作者（JTAC），以允许将网状物手动地导向由激光照射的目标，从而将识别器的目标识别。可以预先选择激光码来跟踪特定的指示符，或者，跟踪器可以在其视野内读出激光点的代码或代码。
