ABSTRACT:
In a microwave holographic device, the main lobe of a microwave antenna is spatially scanned to receive a microwave signal reflected from an object. The received microwave signal is mixed with a reference signal to generate two-dimensional electric information, synchronized with the scanning. The two-dimensional electric information is used to change the optical properties of an electrooptic material, and then the optical property changes are read out to obtain a holographic image.
