摘要： A method for increasing the resolution of confocal images acquired through an image guide whereof the distal end is associated with an optical head for focusing the laser beam emitted by the image guide in an observation object. For a given position of the optical head, the method includes the following steps: producing a plurality of acquisitions through the image guide, each acquisition being produced for a specific spatial shift of the distal end of the guide image relative to the optical head which remains stationary; transforming the data of each acquisition into a point cloud; registering each scatter plot relative to a point cloud taken as reference; superimposing the thus registered point clouds; and reconstructing a final image from the superimposition. Advantageously, a controlled piezoelectric tube is used arranged about the distal end of the image guide to shift the latter.

摘要： An optical variation device includes a liquid-crystal element having optical properties that control the propagation of light and two substrate plates arranged on either side of the liquid-crystal element. The two substrate plates are covered respectively with first and second control electrodes. Each electrode has a substantially central opening referred to as the optical aperture. The device also has a layer of a material arranged between the electrodes and filling the optical aperture. The material has a surface resistivity of 10 kΩ/square to 10 GΩ/square and at least the first electrode is divided into a plurality of portions forming sub-electrodes suitable for simultaneously receiving different potentials.
