【摘要】 <正> 各种光学调整机构的设计,同其它的光学仪器一样,应当符合运动学原理,这是从事光学仪器设计的人们所共知的。但是,在目前的光学实验室里的许许多多光学调整机构中,有的简单可靠,调整轻巧,有的笨重复杂,调节困难。这种差异原因是多方面的,但运动学原理应用不当是其中很重要的因素。 任何一种光学仪器在设计的过程中,首先要决定的是这个零件或组合件本身的运动。一般来说,这些零件或组合件总是可以抽象为一个刚体,因此我们要考虑的是刚体在空间任一瞬时的运动。更多还原

【Abstract】 Some principles that must be taken into account in the design of adjusting mechanisms for optical instruments are described based on tenets of kinematics. A two dimensional adjusting mechanism for optical instruments was designed and a brief analysis was made on this system. Facts show that this two dimensional adjusting mechanism for optical instruments has the advantages of not only simple structure, easy processing, but also convenient adjustment, stability and reliabilty.更多还原
