    摘要： The present invention relates, generally, to reporting the approximate three-dimensional orientation of the steerable distal portion of an endoscope to the user of the endoscope. More particularly, the present invention relates to a system and method for providing the endoscope-user a display from which to more easily determine the approximate three-dimensional orientation of the steerable distal portion of the endoscope, thereby facilitating navigation of the endoscope. The present invention also relates to a system and method for limiting the amount the steerable distal portion can bend overall to reduce or eliminate the user's ability to over-retroflex the steerable distal portion of the endoscope.

    摘要： Apparatus and method for controlling the length of a laser cavity comprises a laser diode that is configured to produce a beam of energy, the laser diode has a first end and an output end, the first end being in optical communication with a highly reflective mirror. A wave guide having a receiving end and a transmission end is also provided, with the wave guide being comprised of an electro-optical material, wherein the receiving end is in optical communication with the output end, and the transmission end is in optical communication with an output coupler. A plurality of electrodes are disposed along a longitudinal axis of the wave guide, wherein the voltage on each electrode is independently controlled to alter the index of refraction of the wave guide at a position adjacent each electrode. A polarizer is also provided with respect to the transmission end, with the polarizer configured to attenuate the beam of energy.

    摘要： A method and system are disclosed for synthesizing an electric field. In accordance with exemplary embodiments of the present invention, an electric field that changes across a distance in space is synthesized by applying voltage levels at several locations independently of one another. The independence in voltage levels allows the electric field that is synthesized to be made periodic or aperiodic. Such a synthesized electric field can be changed at any time for use in, for example, a tunable laser. According to an exemplary embodiment, the electric field is used to change the refractive index of an electro-optic substance in an optical filter. Such an optical filter can be used as part of, for example, a wavelength agile laser, an optical add drop multiplexer, an optical switch, or the like. Such an optical filter can also be used for dynamic power balancing, dynamic gain equalization, or the like.
