Abstract

Complex radiation pattern measurements of cameras for astronomical observatories are advantageous over total power radiation pattern measurements because of the wider range of analysis they allow. Probing both the amplitude and phase structure of the camera allows direct comparison between the measured field and electromagnetic simulation data, and allows propagation from the measurement plane to parallel planes along the optical axis. Initial results of laboratory characterization of complex radiation pattern measurements of a 350 GHz, 880 pixel microwave kinetic inductance focal plane array are presented here. The multiplexing readout allow the whole array to be measured with just two beam pattern scans. This allows rapid characterization of a large field camera, comparable to that required by current, planned, and future instruments.
