The assignment of aberration tolerances for optical systems suffering from wave-front aberrations greater than λ/4 is worth further studying. In this paper it is shown that "low" contrast resolving power of optical systems can be taken as an appropriate criterion for assessing image quality, where the optical transfer function can be evaluated approximately in terms of the sums of Legendre polynomials. Accordingly, the best program of aberration correction and tolerences in the case where certain aberration constants are inevitably present and others are adjustable in optical design can be obtained. The results so obtained as applied to aberrations of small magnitude comparable to λ/4 conform well to the Strehl Deffinitionshelligkeit method.

Analysis of the low frequency response of automatic balancing D-C amplifier with mechanical chopper is illustrated by a typical circuit in this paper.The analysis of dynamic response of the modulation and the demodulation circuits and the auxiliary car- rier wave amplifier have been considered more in details.The analysis is based on solving difference equations since the intrinsic working process behaved by the M-D M circuits using mechanical chopper is more accurately described by difference equation other than by differential equations. In this paper,the modulation and demodulation coefficients kM and k of the M-D M circuits and their transfer functions are derived.Besides,an analysis is given to the R-C coupled carrier amplifier and the obtained result tells us that if the parameters of amplifier are exactly choiced,the conventional type low frequency A-C amplifier may be considered as ideal amplifier as to the amplification of modulated wave amplitudes. The results derived in the paper may be used as a guidance for selecting parameters in design such type D-C amplifiers. Selfexcited low frequency oscillation of the automatic balancing D-C amplifier used as a computing operational amplifier is discussed.

本文结合一个典型线路对带有机械振子的自动稳零直流放大器的低频特性,进行了分析,并且着重分析了调制解调辅助放大器对缓变信号的频率响应.所用方法是差分方程求解法,因为用差分方程来描述具有机械振子的调制解调线路的固有工作过程,要比用相同的初始条件的微分方程来描述更为准确.文中推导出调制及解调线路的调制系数 k、解调系数 k 以及它们的传递函数.此外,对放大调制波的阻容耦合放大器也进行了分析.分析结果说明,如果放大器耦合回路的参数选择得合理时,则此放大器对缓变信号的调制波可作为理想放大器来处理.文中所得结果可作为设计该类型放大器时选择参数的参考.此外,本文对于采用自动稳零直流放大器作运算放大器时可能产生的持续低频自激振荡问题,也进行了讨论.
