对测定薄透镜焦距误差的探讨

on the determination of errors in thin lensˊfocal distance

讨论了在非理想状态下,即薄透镜仅存在光心误差的情况下,对高斯法和共轭法测焦距f进行推导,指出高斯法和共轭法产生的误差是一样大的,并推导出产生△f最小的条件．

This paper disuissed the deduction of the focal distance f using the Gauss method and the total yoke method in an imperfect situation, namely a situation where thin lens merely involve light core errors. It was pointed out that the errors caused by the Gauss method and by the total yoko method were similar. Besides, the minimum condition for the △f was also deduced.
