▎ 摘　　要

NOVELTY - The method involves manufacturing (101) graphene from laser element, and setting a periodic micro-nano structure. Electrical testing is carried out (103) for graphene micro-structure, and graphite alkene transport line is detected. The infrared detecting spectral line peak value is separated (104) by regulating grid voltage. The extracted background is collected (105), and the gate voltage (Vg) is regulated. Message spectrum is collected. The need for determining the preset range is detected, and the Vg is gradually increased so that the intrinsic signal in masked peak is revealed. USE - Graphene plasmon enhanced infrared spectrum detection based spectral line peak value separating method. ADVANTAGE - The need for determining the preset range is detected, and the gate voltage is gradually increased so that the intrinsic signal in masked peak is revealed. DESCRIPTION OF DRAWING(S) - The drawing shows a block flow diagram illustrating the graphene plasmon enhanced infrared spectrum detection based spectral line peak value separating method.
