    • A pellicle which exhibits an excellent retaining performance of immobilizing extraneous matter such as dust floating in the space enclosed with the pellicle and a mask, and which has on the inner side of a pellicle frame an adhesive layer having a resistance to short wavelength light, such as excimer light. This pellicle has a pellicle frame, a pellicle film formed on one side of the pellicle frame, and an adhesive layer formed on the inner side of the pellicle frame and containing a greaselike fluorocarbon resin.

    • The drift of an OTDR main part and the drift of a monitor-object optical fiber are measured and the difference betweem then is calculated to obtain the true drift of the monitor-object optical fiber in order to perform automatic monitoring of the monitor-object optical fiber even if signal level fluctuation caused by the environmental condition change, etc. exists on the OTDR main part side. The data on a reference optical fiber are measured by the OTDR main part beforehand and stored and the difference between the stored data and the data which are obtained by a present measurement is obtained to obtain the drift of the OTDR main part. The initial data of the monitor-object optical fiber are measured beforehand and the difference between the initial data and the datum which is obtained by a present measurement is obtained to obtain the drift of the monitor-object optical fiber.
    • 测量OTDR主要部分的漂移和监视对象光纤的漂移,并计算出之间的差异,以获得监视对象光纤的真实漂移,以便对监视对象光学系统进行自动监视 即使OTDR主要部分存在由环境状况变化引起的信号电平波动等的光纤。 预先通过OTDR主体测量参考光纤上的数据并存储,并且获得存储的数据与通过本测量获得的数据之间的差异,以获得OTDR主要部分的漂移。 预先测量监视对象光纤的初始数据,并且获得通过本测量获得的初始数据和数据之间的差异,以获得监视对象光纤的漂移。
