Abstract

We have improved the resolution of our laser optical feedback imaging (LOFI) setup by using a synthetic aperture (SA) process. We report a two-dimensional (2D) SA LOFI experiment where the unprocessed image (i.e., the classical LOFI image) is obtained point by point, line after line using full 2D galvanometric scanning. The 2D superresolved image is then obtained by successively computing two angular SA operations while a one-dimensional angular synthesis is preceded by a frequency synthesis to obtain a 2D superresolved image conventionally in the synthetic aperture radar (SAR) method and their corresponding laser method called synthetic aperture ladar. The numerical and experimental results are compared.

When αx=0 and αy=0, if there is no misalignment, the center of the Gaussian laser beam successively reaches the two galvanometric mirrors on their rotation axis and finally the target on the origin of our experimental coordinate system (x=0, y=0, z=0). If we consider a laser misalignment, the final position of the Gaussian laser beam center is given by (Δx, Δy, z=0).
