    摘要： A fiber optic probe system includes a fiber optic probe and a carrier cable coupled to the probe. The carrier cable includes an excitation fiber for receiving excitation light and supplying a portion of the excitation light to the fiber optic probe, a return fiber for receiving detected light from the probe, and a directional coupler coupling the excitation fiber with the return fiber. The directional coupler is situated near an end of the carrier cable which is closest to the probe. A plurality of these fiber optic probes can be multiplexed using a plurality of carrier cables, each cable having a respective excitation fiber for receiving excitation light and supplying the excitation light to a respective one of the plurality of fiber optic probes.

    摘要： The instant invention is directed in general to optical systems in which a laser beam is injected into the end of an optical fiber and, more specifically, to laser materials processing systems in which a high power laser beam is injected into the fiber input end for transmission to a remote end of the fiber where materials processing is performed with the emitted beam. In a preferred embodiment of the instant invention, an injection chamber is used to isolate the optical fiber injection end from the surrounding air by enclosing the optical fiber injection end, and providing a gas purge to reduce the air concentration and to keep dust from entering or settling on the optical fiber injection end. This preferred embodiment prevents the ionization of the air surrounding the fiber injection end, thereby preventing the damaging effects of ionization which often occur during optical fiber injection processes.

    摘要： An imaging system responsive to focused laser light includes a focusing lens for focusing the laser light and a mirror having a reflective side, a non-reflective side, and a hole for passing a predetermined portion of the laser light from the focusing lens through the non-reflective side. A fiber probe excites and couples fluorescence from an analyte. The fiber probe has a fiber front face for receiving laser light through the hole and for directing the fluorescence to the reflective side of the mirror. Optical devices for imaging the portion of the fluorescence reflected by the mirror to form an image of the fiber front face are provided, as well as an optical stop having an aperture in the image plane of the imaging means for reducing undesired light from the imaging means before reaching a detector. The mirror is angled for directing substantially all fluorescence from the the fiber probe into the imaging means rather than back toward the fiber probe.

    摘要： The present invention provides methods and systems for efficiently computing optimal optical launch powers for meshed optical networks. The present invention can be utilized to find optimal launch powers for multiple wavelengths in a meshed dense-wave division multiplexed (DWDM) system. Generally, the present invention ensures Q exceeds a threshold for OSNR, and then the launch powers are optimized based on nonlinear penalties. If Q is below the threshold, DWDM equipment changes/additions are incorporated to provide adequate OSNR. The present invention provides a computationally efficient mechanism to optimize launch powers in 10 Gb/s, 40 Gb/s, 100 Gb/s, etc. highly-meshed optical networks.

    摘要： Disclosed are flow separation detectors and, more particularly feedback sensor arrangements adapted to provide for the measurement of surface aerodynamic flow phenomena, and especially with regard to aerodynamic flow separation which is encountered over a surface. In order to obviate or ameliorate the electrical energy requirements in the provision of feedback sensor arrangements, particularly such which are employed for a closed-loop control of aerodynamic flow separation; for instance, that on the wing of an aircraft wherein there can be encountered a breakdown of a boundary-layer flow which may adversely affect the performance of the aircraft, provided is a novel system of flow separation sensors which are based on fiber optics and which may be employed for separation feedback control. In particular, the sensors which are based on fiber optics may employ an optical tuft arrangement based on the thermal/fluidic principles of the electrical thermal tuft, but with the employing of fiber optics signal and energy transmission instead of electronics. To that effect, the light transmitted through the fiber optics is adapted to be converted into heat enabling a packet of heated fluid to be convected in the direction of a predominant aerodynamic flow, and to impact or contact one of the temperature sensors which are based on fiber optics at a small following time interval, so as to provide the required information concerning aerodynamic flow separation.
