Abstract
A new system for millimeter wave electronic imaging is described. This system utilizes a spatial light modulator in the focal plane of the collection optics. Each pixel of the modulator is driven by a specific high duty cycle modulation function provided by a modulation function generation circuit. Thus the throughput radiation at each pixel is uniquely labeled(encoded). A post modulation detector sums the signal from all the pixels. Subsequent to detection, the appropriate transform of the sum signal yields specific pixel throughput radiation intensity levels. Several configurations are described including one transmittance configuration and two reflectance configurations. Three specific millimeter wave transmittance embodiments and one reflectance embodiment are also described.
