ALBEDO in Fast confocal fluorescence imaging in freely behaving mice: Supplementary Information
"We tested one device composed of a deformable mirror and a multimode fiber (Albedo System, high frequency version, Errol Laser) that allows projecting successive intensity patterns with a resulting speckle contrast of 3% on a 62µs time window (Fig.1C). Transmission of the device is about 50%. We introduced this system on our optical setup and illuminated the DMD with these fast varying speckle patterns. We then measured the 3D intensity distribution of the illumination patterns and found that the inhomogeneities were strongly reduced (Fig.1A, right). "
