1. one kind can modulation period polymethylmethacrylate fiber grating preparation method, comprise signal generator 1, high-voltage dc stabilization pressuring power 2, liquid container 3, polymethylmethacrylate chloroformic solution 4, stainless steel spinning head 5, receiving electrode plate 6, recurrent pulse high-voltage signal 7, polymethylmethacrylate fiber grating 8, high-voltage signal 9, low-voltage signal 10, it is characterized in that:

  • the modulation frequency range of signal generator 1 is 25MHz, square wave periodic pulse signal can be produced, this periodic pulse signal is loaded on high-voltage dc stabilization pressuring power 2 as low-voltage control signal and produces recurrent pulse high-voltage signal 7, the voltage regulation limits of high-voltage dc stabilization pressuring power 2 is 0V-30KV, when recurrent pulse high-voltage signal 7 is loaded into after on stainless steel spinning head 5 and receiving electrode plate 6, the polymethylmethacrylate chloroformic solution 4 be loaded in liquid container 3 can spray from stainless steel spinning head 5, after being exposed to air, chloroform in polymethylmethacrylate chloroformic solution 4 can volatilize rapidly, form polymethylmethacrylate chloroform colloidal sol, and along with the modulation of high-voltage signal 9 and low-voltage signal 10, produce the polymethylmethacrylate colloidal sol fiber grating of diameter periodically-varied, after chloroform volatilizees completely, the polymethylmethacrylate fiber grating 8 obtaining solidifying can be collected on receiving electrode plate 6.
