  • PASSIVE MILLIMETER WAVE IMAGE CONVERTER
    Publication number: 20150122994
    Abstract: An imaging system is provided. The system includes a receiver to passively receive a millimeter wave (MMW) power level input from a scene and generates an analog output signal. A driver circuit receives the analog output signal and generates a drive output signal based on the amplitude of the analog output signal. A wavelength converter generates a light intensity output is a replica of a portion of the scene associated with the MMW power level input at a different wavelength range than the MMW power level input wavelength range.
