THREE-DIMENSIONAL RECONSTRUCTION OF A MILLIMETER-WAVE SCENE BY OPTICAL UP-CONVERSION AND CROSS-CORRELATION DETECTION

摘要

An apparatus and method may be used to create images, e.g., three-dimensional images, based on received radio-frequency (RP), e.g., millimeter wave, signals carrying image data. The RF signals may be modulated onto optical carrier signals, and the resulting modulated optical signals may be cross-correlated. The resulting cross-correlations may be used to extract image data that may be used to generate three-dimensional images.

1. A method of imaging, including:
modulating a plurality of radio-frequency (RF) signals bearing image information onto a corresponding plurality of optical signals to obtain a corresponding plurality of modulated optical signals; obtaining cross-correlations of the plurality of modulated optical signals; and processing the cross-correlations to generate an image.
