Millimeter wave instant photographic camera |
摘要 |
A photographic camera (10) that generates still photographs or images of a scene by detecting millimeter-wave radiation (16). The camera (10) includes an imaging lens (14) that collects the millimeter-wave radiation (16) and focuses the radiation on a plurality of receiver modules (32) positioned in the focal point of the lens (14) where each receiver module (32) includes a plurality of direct detection millimeter-wave receivers (36). In one embodiment, the plurality of receiver modules (32) are mounted on a single sensor card (28), where the receiver modules (32) on the card (28) are aligned in one direction. Each receiver (36) includes detector circuitry that detects the radiation of a pixel in the scene. Electrical signals from the receiver modules (32) are sent to a processing unit (38) on the sensor card (28). In one embodiment, the radiation (16) collected by the lens (14) is directed to a scanning mirror (18) that scans across the scene at a predetermined rate to generate the entire image. Alternately, the sensor card (28) can be moved relative to the mirror (18) to provide scanning of the image.
