1. A handheld, broadband terahertz (THz) multiple dimensional scanner comprising:
a lens for focusing light on a target, the lens being fixed in a position in a housing;
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 per a scan of the target, 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.
