Combination optical and millimeter wavelength camera

A method for capturing a detector image and optical image, the method comprising:

• providing a detector device that includes a digital optical camera having an optical field-of-view defining an optical image perimeter, a millimeter wavelength (MMW) camera having an MMW field-of-view, a microprocessor and non-transitory memory;
• capturing a digital optical image of a subject with the digital optical camera;
• storing the digital optical image in the non-transitory memory;
• taking a plurality of MMW images of a plurality of different portions of the subject;
• and
• overlaying the plurality of MMW images over the digital optical image within the optical image perimeter until at least a portion of interest of the digital optical image is essentially completely overlaid with a contiguous assembly of the MMW images.

A combination camera detector device comprising:

• a digital optical camera possessing an optical camera field-of-view, the digital optical camera configured to capture an optical image of a person;
• a millimeter wavelength (MMW) camera possessing an MMW camera field-of-view that is less than or equal to the optical camera field-of-view, the MMW camera configured to capture a plurality of MMW images wherein each of the MMW images is of a different portion of the person,
• the MMW camera pointing in a direction that is within the optical camera field-of-view;
• a microprocessor and non-transitory memory operable with a display;
• and
• an overlay algorithm configured to overlay the plurality of MMW images over the optical image in a combined image, the combined image is an overlay of each of the plurality of MMW images matched to the optical image, the overlay algorithm retained in the non-transitory memory and executed by the microprocessor.
