In 3d scanning system based on dot laser, artificial neural networks are used for calibrating the distortion of CCD range sensor.
在点状激光三维扫描技术中，用线阵CCD采集深度坐标，用前馈型人工神经网络对深度坐标进行非线性修正。
Often the projected light dot on a laser pointer is too small to be seen effectively.
通常激光指物棒中设定好的激光点太小了，显示的效果不是很好。
No, because nothing is actually crossing the surface of the moon - the dot isn't an actual object, it is just a series of photons in the laser beam hitting the surface.
其实不是这样，这是因为此时并没有什么实际的东西真正地横跨了月球的表面-亮点不是一个实体，它仅仅是击中月球表面激光束里一系列的光子。
There are three main types of printers? Dot matrix, inkjet and laser.
打印机主要有三种类型？针式、喷墨和激光。
Many laser measuring devices have setting which shows minimum and maximum dimensions; the operator must merely scan the dot along an edge. This is helpful for taking diagonal measurements.
许多激光测量设备有显示最小和最大尺寸的设定；操作者必须只能沿着边缘点扫描。在测量对角线长度的时候这一点非常有用；
This category includes video display adapters, dot-matrix printers, and laser printers.
这类包括视频显示卡，点阵式打印机和激光打印机。
For example, you might choose a laser printer instead of a dot matrix printer.
例如，您可能选择激光打印机而不选择点阵打印机。
Quantum dot optic microcavity device had potential application in field of quantum information technology using as the low threshold laser and single photon light source etc.
量子点光学微腔器件在低阈值激光器和单光子光源等量子信息处理技术领域有重要的应用前景。
Print out a draft for me to look at on the dot matrix printer and if that's alright, print the final copy on the laser printer.
用点矩阵印表机印一份初稿给我看，如果无误，就用激光印表机印出完稿。
A mathematical model for an ovoid spiral scanning system with airborne laser for underwater object detection is developed and a scheme for dot matrix uniformity optimization is proposed.
建立了机载激光水下目标探测中的卵形螺旋线扫描系统的数学模型，提出了点阵均匀性优化方案。
Avoid laser pointers (that red dot moving all over the place will give you away) and while it's okay to speak from notes, don't use loose paper, which "will flap like a sail."
千万不要拿激光教鞭（那个红点四处乱窜，会让你的紧张显露无疑）。在演讲时参考笔记是可行的，但不要使用松软的纸张，因为它们会“像船帆一样来回摆动。”
