Abstract :
Our goal is to perform real time detection and direct high resolution imaging of millimeter continuum sources with multiple aperture interferometry. This is done by coupling a millimeter wave array to an optical interferometer via an electro-optic modulator array. We choose a concentric ring antenna array to efficiently snapshot sample the Fourier plane uniformly and isotropically, and minimize the maximum sidelobes of the point spread function. For direct imaging, we implement a Fizeau interferometer backend.
