The invention relates to a method for measuring the chirality of a carbon nanotube in situ, comprising the steps of: S1, providing a carbon nanotube to be tested; S2, placing the carbon nanotube to be tested in a coupling liquid; S3, providing a white incident light having a continuous spectrum, wherein the carbon nanotube to be tested undergoes resonance Rayleigh scattering under the irradiation of the incident light; S4, observing the carbon nanotube to be tested by using an objective lens as a water microscope, and obtaining Position information of the carbon nanotube to be tested, the water mirror is immersed in the coupling liquid during observation; S5, obtaining a resonance Rayleigh scattering spectrum of the carbon nanotube to be measured, and obtaining the Rayleigh scattering spectrum information according to the resonance The chiral index of the carbon nanotubes to be tested. The invention also relates to a device for measuring the chirality of a carbon nanotube using the method. |
