摘　　要：通过分析反射式光学系统的特点,在现有透射式光学系统中心偏测量仪的基础上,提出了适合该系统中心偏测量的方法,分析了球心像的观察条件,并推导出反射系统中心偏的计算公式,从而形成了一个完善的反射式光学系统中心偏测量体系。该方法能获得与透射系统中心偏测量相同的精度,操作方法也基本相同。A new method of decentration measurement that suit reflective optical system is put forward on the basis of transmittance optical system centration error measuring instrument in existence. Observation condition of sphere centration image is analyzed, and decentration calculation formula is derived. Consequently a decentration measurement system for reflective optical system is formed. This method has the same accuracy as transmittance decentration measurement, and the operation is basically the same.
