Abstract We present a miniature oblique back-illumination microscope (mOBM) for imaging the microcirculation of human oral mucosa, enabling real-time, label-free phase contrast imaging of individual leukocytes circulating in the bloodstream, as well

Miniaturization of imaging systems has become an important requirement for studying the brains of freely behaving animals (mice, birds, etc.). The author presents a 1-photon miniscope device with significant mechanical (weight: 1.3g, small size: 10mm

We present a motion-free system for microendoscopic imaging of biological tissues at variable focal depths. Fixed gradient index and electrically tunable liquid crystal lenses (TLCL) were used to build the imaging optical probe. The design of the TLC

Liquid crystalline (LC) materials are user friendly materials for electro optics applications [1], the most popular of which is the flat panel display [2]. Another interesting development, involving LCs, was the electrically variable lens that alread

We describe the use of stacked electrically tunable liquid crystal lenses (TLCLs), along with rod gradient index (GRIN) fixed focus lenses, for endoscopic applications. Architectural and driving conditions are found for the optimization of total aber

Azobenzene dye doped reactive mesogen is used as thin photo control layer to align permanently nematic liquid crystal molecules. It is shown that, even in the case of a non mesogenic dye, the reactive mesogen matrix follows its photo induced reorient

We describe the detailed study of a polymer stabilized liquid crystal compound, which was created by using a reactive (monofunctional) azobenzene mesogenic guest and a nematic liquid crystal host. The resonant interaction of light with the azobenzene
