Wave-shifting optical fiber reverse mode method

The invention discloses a wave-shifting optical fiber reverse molding method. The method comprises the following steps: step 1, preparing a pouring sealant; 2, eliminating bubbles in the pouring sealant; 3, pouring the de-foamed pouring sealant into a first mold bottom plate; 4, a plastic scintillator is arranged on the surface of the pouring sealant after mold reversing; 5, drying; 6, demolding, wherein a groove is formed in the surface of the demolded pouring sealant under the action of the first mold bottom plate; 7, embedding the wave-shifting optical fiber with the fixed length into the groove in the surface of the cured pouring sealant; 8, secondary glue preparation and defoaming; ninthly, the pouring sealant in the seventh step and the wave-shifting optical fiber assembly are loaded into a second mold bottom plate; 10, pouring the pouring sealant in the step 8 into a second mold bottom plate; eleventhly, secondary drying and demolding are conducted. The method is simple in step, reasonable in design, c
