Imaging apparatus ( 20, 44 ) includes an array ( 22 ) of optical sensing elements ( 24 ), characterized by a pitch, which is adapted to generate a signal in response to optical radiation that is incident on the elements. Objective optics ( 26, 46 ), which have an optical axis ( 134 ) and are characterized by a cylindrical symmetry about the axis, are arranged to focus the optical radiation from an object onto the array with a point spread function (PSF) having an extent greater than twice the pitch of the array at an optimal focus of the objective optics. |
