Claim:
1. A millimeter wave three dimensional holographic scan imaging apparatus, comprising: a first millimeter wave transceiver module comprising a first millimeter wave transceiver antenna array for transmitting and receiving a first millimeter wave signal; a second millimeter wave transceiver module comprising a second millimeter wave transceiver antenna array for transmitting and receiving a second millimeter wave signal; a first guide rail device, to which the first millimeter wave transceiver module is connected in slidable form, such that the first millimeter wave transceiver module is moveable along the first guide rail device to perform a first scan on an object to be inspected; a second guide rail device, to which the second millimeter wave transceiver module is connected in slidable form, such that the second millimeter wave transceiver module is moveable along the second guide rail device to perform a second scan on the object to be inspected; a driver configured to drive the first millimeter wave transceiver module to move along the first guide rail device and/or to drive the second millimeter wave transceiver module to move along the second guide rail device; and a constrainer configured to constrain kinematic relation between the first millimeter wave transceiver module and the second millimeter wave transceiver module such that the first millimeter wave transceiver module and the second millimeter wave transceiver module only move in directions opposed to each other, wherein the driver comprises a first driver configured to drive the first millimeter wave transceiver module directly, the first millimeter wave transceiver module being connected to the first guide rail device by the first driver, and the driver also comprises a second driver configured to drive the second millimeter wave transceiver module directly, the second millimeter wave transceiver module being connected to the second guide rail device by the second driver, and wherein the first millimeter wave signal and the second millimeter wave signal have different frequencies from each other during at least 50% of an entire period of scanning the object to be inspected by both the first millimeter wave transceiver module and the second millimeter wave transceiver module.
