Abstract :
We present the results of development of a 3-mm wavelength video imaging system. The external EM radiation is detected with an 8 × 8 detector array illuminated by an aspheric lens, which forms an image, and a digital control unit. Some measured characteristics of the array elements (antenna element patterns, sensitivity, etc.), optical characteristics of the imaging system (point spread function, resolution, field of view, etc), as well as parameters of the digital unit (data processing and transmission rates) are given. The developed system was used in the experiments for imaging of simple objects (one or several metal spheres of different diameters) by means of reflected monochromatic signal detection.
