Under astigmatism even narrow parallel light beams will not combine into one point . 有象散存在时甚至很窄的平行光束都不能会聚在一点。
A parabolic concave mirror can converge parallel light rays to its focus , and also collimate light rays that pass through its focus 抛物面凹镜会把平行而来的光线聚集在一点焦点,亦会把源自焦点的光线平行向外反射。
A parabolic concave mirror can converge parallel light rays to its focus , and also collimate light rays that pass through its focus 抛物面凹镜会把平行而来的光线聚集在一点(焦点) ,亦会把源自焦点的光线平行向外反射。
When voltage is applied , however , these same molecules arrange themselves in a specific direction in such a way as to permit parallel light to pass through the glass 当液晶体份子任意地排列时,光线就不能透过玻璃.但当液晶体份子排列成某一方向,平衡的光线就可透过玻璃
A type of small - sized interferometer is reported , which makes use of the coupling of optical fiber and gradient index lens ( grin ) to form parallel light beams 摘要介绍一种超小型光纤导光干涉仪,它利用光纤和自聚焦透镜的耦合来形成平行光路,利用半反和全反光学膜片分光。
A concave mirror reflects parallel light rays so that they meet at the so - called focal point . ( if you try to use such a mirror to start a fire in sunlight , you place the tinder at the focal point . ) the distance from the mirror to the focal point is its focal length 凹面镜反射平行光,让光线汇聚到所谓的焦点(如果你想用这种镜子在日光下起火,就要把易燃物放在焦点上) ,从镜面到焦点的距离就是焦距。
So the base decided to rebuild the system , in the rebutided detect - calibrating system , closing control technique has been adopted and the guiding accuracy has been greatly improved . at the same time , it has adopted multiple parallel light - pipeline scanning technique , and the efficiency of detect - calibrating has remarkably enhanced 在改造后的检校系统中,采取了闭环控制,提高了引导精度,同时采用单航路多平行光管的扫描,提高了检校效率。
