Latest Patents

- **Multiphotonic microscopy method and device.** This invention concerns a method and device for multiphotonic microscopy.

- **Method and system for calibrating a spatial optical modulator in an optical microscope.** This invention describes calibrating an optical device that uses a spatial optical modulator. The system includes a high-numerical-aperture lens, a camera positioned in a plane optically conjugate to the lens’s focal plane, and a spatial optical modulator in the optical path. The method acquires three-dimensional intensity images of the point spread function, reconstructs the beam’s amplitude and/or phase profile using a phase-diversity algorithm, and determines how individual modulator elements affect that profile.
