  • Deformable mirror apparatus
    Publication number: 20060104596
    Abstract: An apparatus including a tip-tilt mount, a mirror mounted in the tip-tilt mount, the tip-tilt mount determining an orientation of the mirror, and a forcing frame attached to the mirror and applying at least one bending moment to the mirror. Optionally, the forcing frame includes a vacuum cup connected to the mirror. Optionally, the forcing frame includes a bridge connected to the mirror. Optionally, the apparatus further includes an interferometer including the tip-tilt mirror mount, the mirror, and the forcing frame.

  • Fiber grating-based detection system for wavelength encoded fiber sensors
    Patent number: 5410404
    Abstract: An apparatus for the determination of the wavelength and the detection of velength shifts in wavelength-encoded fiber sensors, such as Bragg grating sensors. The apparatus is implemented in fiber and uses a pair of tuned fiber gratings to provide a filter type function that tracks the wavelength component of a signal from a wavelength-encoded sensor.
