posit ion sensit ive detector non-st raightness spectrum analysis hanning lowpass filter noise
A novel method for measuring the non-st raightness of straight tube w ith PSD is briefly introduced in this paper. The f requency spectrum is used to analyze theoret ical nonst raightness model and experimental data . Herefrom, the characterist ic of main-occupancy of low-f requency is concluded. In order to filter the high-f requency noise, Hanning Low-pass Fi-l ter is ut ilized to overcome the dif ficulty in filtering hig h-frequency noise of space domain sig nal such as the non-straig htness of st raight tube with elect ronic filter.
