Terahertz three-dimensional spectral scanner apparatus and method of using same

A broadband terahertz (THz) multiple dimensional imaging system comprising:

• a handheld scanner comprising:
• a lens for focusing light on a target;
• a 2-Dimensional (2D) gimbaled mirror, the 2D gimbaled mirror comprising a single mirror mounted in a frame, a first motor and a second motor, the first motor and the second motor coupled to the frame, the mirror rotatable in a first axis of rotation and a second axis of rotation under a control of a motor controller and a system controller to control the single mirror to execute a point scan of light on the target in two dimensions to generate an image, the first motor corresponding to the first axis and the second motor corresponding to the second axis, the single mirror positioned at a focus of the lens;
• an emitter configured to emit the light which is incident on the single mirror and the target;
• and
• a detector configured to detect light reflected from the target;
• fiber optic cables connecting to the emitter and the detector;
• signal cable connected to the detector;
• power cable connected to the emitter;
• the motor controller coupled to the first motor and the second motor and the system controller, the motor controller configured to cause the first motor and the second motor to cause the mirror to rotate about the first axis and the second axis to execute the point scan of light on the target over a plurality of different positions in the two dimensions to create the image based on signals from the system controller,
• the system controller further configured to control the emitter to emit the light and generate the image of the target based on the reflected light;
• and
• a display for displaying the image of the target generated by the system controller.
