    • Abstract
  • Based on the relations between the imaging quality with point spread function and optical transfer function, taking Golay-3 array as an example, the theoretical simulation and experiment for the optical synthetic aperture imaging technique are implemented in spatial and frequency domains. The point spread function and optical transfer function is the basis for optical synthetic aperture design and optimization. The imaging of complex objects can be obtained by the object function convoluting with the point spread function. The point spread function determines the imaging quality. The intensity distribution diagrams of the point spread function were acquired by the digital simulation and simulated experimental. The optical transfer function of optical synthetic aperture system was achieved from the point spread function. The simulation and experimental results are analyzed and compared. The experimental results agree well with the theoretical analysis. It proves the validity of the theoretical analysis.
