An improved scheme for passive synthetic aperture photonic imaging

Abstract:

An improved scheme for passive synthetic aperture imaging is proposed. With this new technique,the radiation signal from field of view (FOV) is received and its frequency is down-converted to intermediate frequency (IF). The IF signals are modulated to light-wave by electro-optical phase modulators and transmitted in fiber. At the end of the fiber,a downscaled fiber array is formed according to the receiver array. The image of FOV is obtained with the fiber array. The principles of passive synthetic apertur...
