Abstract
In a method for imaging using multiple apertures, the present invention uses a wavefront sensor, a phase sensor, and an image processor to construct a high-resolution image without using complex relay optics. A wavefront sensor collects information that allows the wavefront from each aperture to be reconstructed and a phase sensor collects information regarding the relative phase difference between the apertures. An image processor uses the information collected from the phase sensor to correct the phase differences between the apertures, reconstruct the wavefronts from the wavefront sensor data, then coherently sums the wavefronts from each aperture to form a high-resolution image that corresponds to a synthesized aperture that is larger than any of the individual apertures.
