Speckle holography is an observational technique which relies on the presence of a PSF calibration star in the same field as the target of interest to produce images of diffraction-limited resolution and high dynamic range. The observations are simple and efficient, and do not require any specialized hardware beyond an imager capable of being read out fast enough to``freeze" the atmosphere (i.e., frame time ~ 100 mS in the near-IR) and an image scale sufficiently fine to Nyquist sample the telescope's diffraction limit. This poster presents a study of the real-world performance of the technique when used on the 10 m Keck 1 telescope, and describes its application to the study of pre-main sequence visual binary stars.
