  The Keck Planet Imager and Characterizer comprises of a series of upgrades to
the Keck II adaptive optics system and instrument suite to improve the direct
imaging and high resolution spectroscopy capabilities of the facility
instruments NIRC2 and NIRSPEC, respectively. Phase I of KPIC includes a NIR
pyramid wavefront sensor and a Fiber Injection Unit (FIU) to feed NIRSPEC with
a single mode fiber, which have already been installed and are currently
undergoing commissioning. KPIC will enable High Dispersion Coronagraphy (HDC)
of directly imaged exoplanets for the first time, providing potentially
improved detection significance and spectral characterization capabilities
compared to direct imaging. In favorable cases, Doppler imaging, spin
measurements, and molecule mapping are also possible. This science goal drives
the development of phase II of KPIC, which is scheduled to be deployed in early
2020. Phase II optimizes the system throughput and contrast using a variety of
additional submodules, including a 952 element deformable mirror, phase induced
amplitude apodization lenses, an atmospheric dispersion compensator, multiple
coronagraphs, a Zernike wavefront sensor, and multiple science ports. A testbed
is being built in the Exoplanet Technology Lab at Caltech to characterize and
test the design of each of these submodules before KPIC phase II is deployed to
Keck. This paper presents an overview of the design of phase II and report on
results from laboratory testing.
