The phase-apodized-pupil Lyot coronagraph (PAPLC) produces a one-sided dark zone, with, in theory, a 2 λ/D inner working angle at contrasts of 10^-10 and high planet throughput, perfect for future space missions such as the Habitable Worlds Observatory. The two DMs in the wavefront control system serve as the apodizer. We present laboratory results on a segmented telescope pupil in broadband light on the High-contrast imager for Complex Aperture Telescopes (HiCAT) testbed. A Zernike wavefront sensor, which uses the light rejected by the coronagraph, simultaneously measures any high-order aberrations. We report on the achieved broadband contrast within a 10% and 20% bandpass, under natural and artificial environmental conditions.
