Synthetic Aperture Imaging Systems

 
 

Combining optical coherence tomography instrumentation and the principles of synthetic aperture radar (SAR), we have developed a new method, namely ISAM, for reconstructing 3-D optical images—even in regions that are out of focus in the raw data.  ISAM and SAR reconstruction algorithms are based on the same principle, namely that an aperture with high resolution can be computed from several low- resolution apertures. Further development of ISAM may benefit from the long history of SAR, in both reconstruction and hardware. The use of well-developed SAR algorithms such as ground moving target indication, autofocus, automatic target identification, and others can be applied to future ISAM imaging systems, providing automatic detection algorithms or guidance for diagnosis and intervention.
