The disclosed MMW wave sensing camera calibration arrangement that generally includes a millimeter wave camera that uses an energy emission calibration panel as a calibration standard. The MMW camera is positioned opposite the calibration panel in the MMW camera's field-of-view. The calibration panel is held at a constant temperature to provide a standard emission of millimeter waves that is sensed by an MMW sensor to set or otherwise calibrate the MMW camera to a baseline emissivity value corresponding to the panel. The MMW camera is linked to a microprocessor and non-transient computer memory containing a calibration routine that is configured to reset the baseline only when nothing obstructs the calibration panel's field-of-view. A visual display is linked to the MMW camera and configured to display an MMW signature of a metal object that is disposed on a person's body when the person's body is in the field-of-view, the metal object concealed by clothing worn over the person's body.

The disclosed handheld camera device is a combination digital optical and millimeter wavelength (MMW) camera. In contrast to an optical camera, the MMW camera detects frequencies between 3-300 GHz making the MMW camera especially good at seeing metallic objects under garments, such as concealed weapons on a person or in a bag. The MMW camera can be arranged to point in the same field-of-view as the optical camera so that when an MMW image is taken it is automatically framed within the optical camera field-of-view. In certain configurations, the MMW camera takes a plurality of MMW images defined within an MMW field-of-view. In the case where the MMW field-of-view is smaller than the optical camera field-of-view, the multiple MMW images can be stitched together and overlaid on the optical image of the same scene to show a metallic object superimposed over a subject of interest.
