Claim 2:
3. The quadrilateral common-path time-modulated interferometric spectral imaging device according to claim 2, wherein the optical path adjustment device in the optical path adjustment module as a moving mirror comprises a first prism and a second prism, and the optical path adjustment device in the optical path adjustment module as the fixed mirror comprises a third prism and a fourth prism; an exit surface after a beam passing through any one of the first prism, the second prism, the third prism, and the fourth prism is parallel to an incident surface; the first prism and the second prism rotate under the drive of the motor, and a rotation axis of the motor is perpendicular to a propagation direction of the beam; attitudes of the third prism and the fourth prism have angles tilt relative to a perpendicular incident surface of the beam, which is used to compensate for an zero dispersion effect and increase an zero-crossing optical path difference position.
