Abstract
The present disclosure provides a lens assembly, a terahertz wave tomography system and method, and a terahertz wave filter. The lens assembly includes: a first substrate and a second substrate that are oppositely disposed; a seal, wherein the seal, the first substrate and the second substrate enclose a cavity in which a magnetic fluid is filled; and a plurality of electromagnetic generating units disposed on at least one of a first side of the first substrate close to the second substrate or a second side of the first substrate away from the second substrate, wherein at least a part of the plurality of electromagnetic generating units are configured to generate a magnetic field in a case where a voltage is applied to make the magnetic fluid form a Fresnel zone plate pattern.
