( 3 ) the direct slicing data are processed in order to accurately extract and reconstruct the data information of the 2d contours . based on it , the radius compensation of laser beam spot , the filling contours and the optimization of the scanning paths are all implemented ( 3 )通过对直接分层轮廓进行处理,实现了层片轮廓数据的提取、层片轮廓的重建、激光光斑的补偿,以及层片轮廓的填充和扫描路径的优化。
In the paper , both the size of the source and of the beam spot of a extended gaussian beam are considered and their influences on both the lateral and axial resolution of a fluorescent confocal microscopy are studied and calculated based on the power transfer function and three - dimensional pulse spread function 摘要研究一定光源孔径、束斑的高斯光束对荧光共焦显微镜横向、纵向分辨率的影响,导出了荧光功率传输函数、三维响应函数。
The laser beam spot evolution and electron density in the guiding range are evaluated with the burn pattern and the measured conductivity . the above results will be useful in ultrashort laser pulse amplification and future research in ultrashort intense laser propagation in plasmas and ionizing gases 以上研究结果对于超短脉冲激光放大技术研究以及超短超强脉冲激光在低密度等离子体和空气中长距离传输和聚焦研究等具有重要的实用参考价值。
And we also provide a detection method whose precision is on the order of micro radians . all of the above is based on technologies on ccd , dsp digital control and digital procession of images . we design a optical amplifier system matching the specified ccd camera , in order to catch qualified laser beam spot images 本论文对光通信精跟踪的技术进行了论述、分析,在此基础上提出实现十微弧度跟踪精度的精跟踪系统原理样机的设计方案,及能检测微弧度量级的检测方法,这主要基于ccd探测技术、 dsp数字控制技术和数字图像处理技术。
