The non-coaxial array of Q-PV. (a) The design phase distribution of the Q-PV non-coaxial array; (b) The light field intensity distribution in the focal plane; (c) The phase distribution in the focal plane, the blue rectangle boxes out the phase of Q-PV at that position and TC; (d) The partially enlarged phase distributions in the focal plane, dotted lines indicate the position and number of phase fringes.
