提出了一种基于迈克尔逊干涉仪的振动频率匹配（VFM）方法。通过这样做，干扰信号示出具有指示两端之间的频率差的周期的包络。该方法在大气压下得到的谐振频率偏移与参考频率的比值（f/fo）低至1/99720。将带有荧光功能基团的寡核苷酸探针置于悬臂梁上进行质量检测。可在荧光显微镜下检测，以验证其存在。测得质量为575 fg。系统的频率分辨率和质量分辨率分别为0.15Hz和57 fg
We proposed a Vibration Frequency Matching (VFM) method based on the Michelson interferometer with the reference ends vibrating at a fixed frequency. By doing so, the interference signal shows envelopes with period indicating the frequency difference between two ends. This method yields the ratio of the resonant frequency shift to the reference frequency (f/fo) as low as 1/99720 at atmosphere. The Oligonucleotide probe with fluorescence function group attached was placed on cantilever beam for mass detection. It can be detected under fluorescence microscope to verify the existence. The mass was measured to be 575 fg. The frequency resolution and mass resolution of the system proposed are about 0.15 Hz and 57 fg, respectively
