• Photometric characterization of exoplanets using angular and spectral differential imaging (2010, methodology): “It has been extensively studied (Marois et al. 2000), and subsequently tested on sky with TRIDENT on the CFHT (Marois et al. 2005) and with NACO on the VLT (Lenzen et al. 2004).”
• Imaging Spectroscopy for Extrasolar Planet Detection (2002, background): “…of speckle patterns to reduce point-spread function (PSF) halos or recognize planetary signatures within the speckle noise, including the dark-speckle coronagraph (Boccaletti et al. 1998) and the use of dichroics and differencing of speckle images (Racine et al. 1999; Marois et al. 2000).”
• Limits of Adaptive Optics for High-Contrast Imaging (2005, unknown): “Differential imaging techniques based on spectral properties of the source could further increase this factor by up to 102 for simultaneous imaging in 2 bands and 104 for simultaneous imaging in 3 bands (Marois et al. 2000).”
• Imaging Polarimetric Observations of a New Circumstellar Disk System (2001, unknown): “Differential, multi-wavelength, observations (Racine et al. 1999) have been suggested as a – 4 – method to minimize such noise, although their approach may be limited by the chromaticity of the residual noise (but see Marois et al. 2000 for a discussion of this technique).”

• NEAR-INFRARED SPECTROSCOPY OF THE EXTRASOLAR PLANET HR 8799 b (2010, background): “High contrast AO imaging observations are limited by quasistatic speckle noise at small angular separations ( 1′′–2′′), which results from slight imperfections in telescope optics and AO wave front correction (Racine et al. 1999; Marois et al. 2000, 2008a; Oppenheimer & Hinkley 2009).”
