    Abstract: An optical component mount with beam deviation monitoring and beam guiding system using such optical component mounts. The optical component mount has a location for mounting an optical element thereon for operating on the beam and at least one sensor attached to the optical mount at a predetermined position. The predetermined position is selected depending on the state of the optical component mount. The state can be, e.g., a vibrational state or a thermal expansion state. The predetermined position is chosen near or at an anti-node of at least one mode contributing to the state but not at a node of any mode expected to contribute to the state of the optical mount. The state of the optical mount is determined based on the signals obtained from the at least one sensor, which can be an accelerometer in the case of monitoring a vibrational state or a temperature sensor in the case of monitoring a thermal expansion state. The sensor is preferably embedded in the optical mount and the deviation of the beam is then determined from the state of the optical mount. Optical mounts according to the invention can be used in any beam guiding system including but not limited to those found in optical and/or opto-electronic assemblies.

    Abstract: The present invention relates to a torque sensor apparatus and method using variations in the microstructure of an optical waveguide affixed to the surface of a stress bearing member to measure the deflective force applied to the stress bearing member. A signal propagating through the optical waveguide is modified as a result of forces applied to the stress bearing member and to the optical waveguide. Induced changes in the index of refraction and alterations in the critical bending radius value of the optical waveguide result in modulation of the transmitted signal.

    Abstract: Fiber grating environmental measurement systems are comprised of sensors that are configured to respond to changes in moisture or chemical content of the surrounding medium through the action of coatings and plates inducing strain that is measured. These sensors can also be used to monitor the interior of bonds for degradation due to aging, cracking, or chemical attack. Means to multiplex these sensors at high speed and with high sensitivity can be accomplished by using spectral filters placed to correspond to each fiber grating environmental sensor. By forming networks of spectral elements and using wavelength division multiplexing arrays of fiber grating sensors may be processed in a single fiber line allowing distributed high sensitivity, high bandwidth fiber optic grating environmental sensor systems to be realized.

    Abstract: The invention provides a method of sampling M sensors in a fiber optic detector array, by determining a maximum sampling rate possible, and assigning priority to each sensor. Thereafter, available sampling spots are divided into discrete blocks and the sensor of highest priority is assigned sampling slot(s). The remaining sensors are placed in the remaining sampling slots in order of priority, and if a sampling slot is taken, the remaining sensors are placed in the next closest slot. The invention also provides 1D and 2D digital and spatial wavelength domain systems including a plurality of fiber Bragg gratings (FBGs). The FBGs may be illuminated by a plurality of broad band light sources, and coupled thereto by 2null2 couplers. The systems may include a 1D or 2D wavelength dispersion device, and 1D or 2D optically sensitive solid state means for spatially separating the signals at each wavelength reflected by the FBGs.

    Abstract: Optical touch switches are implemented based on the use of light total internal reflection and light scattering concepts. The optical touch switch basically consists of a light source, a light guide, a photodetector, and an electronic controller. The fingertip touching on the touching surface of the optical touch switch leads to the change in electrical current produced by the photodetector. As a result, the electronic control box senses this change of electrical current and allows the electrical load to stay at the desired state. Key advantages include ease of implementation, prevention of the light beam incident directly on the user's eyes, and ability to accept both strong and weak mechanical forces from users.
