▎ 摘　　要

NOVELTY - The device has a charge coupled device (CCD) camera (14) is aligned with the reflected light of a beam splitter (9). The reflected light of a high-reflection mirror (10) is aligned with a filter (11). A photodetector (12) receives the light filtered by the filter. A first graphene mechanical vibrator (1-1) and a second graphene mechanical vibrator (1-2) are adjacently connected in the sample cavity. A grid voltage supply circuit includes a direct current (DC) voltage source. The DC voltage source is connected to the gates of the first graphene mechanical vibrator and the second graphene mechanical vibrator. A pump circuit includes a phase-locked amplifier (17) and a bias device (16). The pump generated by the phase-locked amplifier acts on the grid of the first graphene mechanical vibrator through the bias device together with the DC voltage. A signal extraction circuit includes the phase-locked amplifier electrically connected with the photodetector.
