Abstract:
An imaging apparatus, comprising:a millimeter wave detector having an input port and an electrical output, the detector being responsive to millimeter waves at the input port to produce an electrical signal indicative of the intensity of the millimeter waves; a scanner having a scanner input aligned to an external environment, the scanner including a plurality of central reflectors, each mounted to scan about a respective scan axis through a selected scan angle in response to a common drive signal, each of the scan axes being parallel, each central reflector including a material reflective to millimeter waves, the central reflectors being oriented to direct millimeter waves from an image field to the input port; a signal source coupled to the scanner and operative to provide the drive signal; and an electronic controller having an electronic input coupled to the electrical output, the controller being responsive to the electrical signal indicative of the intensity of the millimeter waves to generate image data representative of the image field.
