  We present a direct imaging study of V892 Tau, a young Herbig Ae/Be star with
a close-in stellar companion and circumbinary disk. Our observations consist of
images acquired via Keck 2/NIRC2 with non-redundant masking and the pyramid
wavefront sensor at K$^\prime$ band (2.12$\mu$m) and L$^\prime$ band
(3.78$\mu$m). Sensitivity to low-mass accreting companions and cool disk
material is high at L$^\prime$ band, while complimentary observations at
K$^\prime$ band probe hotter material with higher angular resolution. These
multi-wavelength, multi-epoch data allow us to differentiate the secondary
stellar emission from disk emission and deeply probe the structure of the
circumbinary disk at small angular separations. We constrain architectural
properties of the system by fitting geometric disk and companion models to the
K$^\prime$ and L$^\prime$ band data. From these models, we constrain the
astrometric and photometric properties of the stellar binary and update the
orbit, placing the tightest estimates to date on the V892 Tau orbital
parameters. We also constrain the geometric structure of the circumbinary disk,
and resolve a circumprimary disk for the first time.
