Fog up a piece of glass with your breath and look through the fogged plate in a darkened room at a white-light point source. 哈气使一片玻璃蒙上一层水雾,并在一个暗间里通过它来观察一个白色点光源。
To do so, a straight line is defined between a point source of light and a detector. 为了这样做,在点光源和探测器之间精确的界定一条直线。
Of or relating to light emitted from a point source and reflected or refracted from a curved surface. 由一个点光源发出并从曲面反射或折射的光的或关于这种光的。
Point-sourc reflector radiator and point source array radiator were adopted to study experimentally the transmission property of ultra-short pulse. (红外辐射)发射型探测器采用了点源(PS)&反射面型及阵列型辐射器对超短脉冲的辐射特性进行了实验研究。
The full parallax CGHs are generated by the point source method and the wave-oriented method without paraxial approximation. 这种全视差计算全息图是由点基元方法和平面波导向法生成并且没有经过旁轴近似。
