Sidelobe reduction via multiaperture optical systems

The impulse responses of multiaperture optical systems can generate large sidelobe irradiances. The purpose of this research was to design multiaperture systems with impulse responses that exhibit sidelobe irradiances less than that of the Airy pattern and central lobe widths no greater than that of...

Description
Summary:The impulse responses of multiaperture optical systems can generate large sidelobe irradiances. The purpose of this research was to design multiaperture systems with impulse responses that exhibit sidelobe irradiances less than that of the Airy pattern and central lobe widths no greater than that of a single large aperture of an equivalent diameter. Multiaperture systems composed of 19, 37, 61, and 91 apertures satisfy these performance criteria. However, the amount of energy in the central lobes of the multiaperture systems was less than that of a single large aperture.
