摘要： The present techniques provide methods and systems for controlling the recording of micro-holograms using multiple counter-propagating light beams over multiple data tracks of a holographic disk. Imperfections in a holographic disk or movement of the disk during a recording process may cause signal beams to deviate from target data tracks. In some embodiments, a tracking beam is directed to a reference layer in the disk. Deviation of the reference beam from a target groove in the reference layer may be indicative of tracking errors. A detector may detect reflections of the tracking beam and generate an error signal in response to detected tracking errors. Servo-mechanical devices may actuate (e.g., radially, tangentially, or axially translate, rotate, and/or tilt) one or more optical components through which the counter-propagating light beams are emitted to compensate for tracking errors.

摘要： A fiber-optic dynamic sensing module comprises a support member, a beam extending from the support member, and a pre-strained fiber Bragg grating sensor and a strain-free fiber Bragg grating sensor mounted on the beam. The pre-strained and strain-free fiber Bragg grating sensors each comprise a Bragg grating inscribed in a fiber. The Bragg grating of the pre-strained fiber Bragg grating sensor is packaged more tightly along a longitudinal direction of the beam than the Bragg grating of the strain-free fiber Bragg grating sensor.

摘要： A blanket or article of wearing apparel for a subject such as an infant. A fiber optic temperature sensing element is integrated into the fabric by a process such as weaving. The temperature sensing element is a optic fiber having inscribed therein one or more fiber Bragg grating sensors such that a light is introduced into the optic fiber and that light directed onto the subject at a grating interface. A return light signal is received, either by a reflectance mode or a transmission mode, where the return light signal has a wavelength shift indicative of the temperature of the subject by Bragg resonant effect. Higher temperature sensitivity is obtained with a metal material of a high thermal expansion coefficient that is coated around the fiber sensor cladding.

摘要： An article includes a stack of display layers including a display layer having a high-shear modulus that is sandwiched between two display layers having a low-shear modulus. The display layers include a light-emitting device that generates heat and light during use. The heat generated by the display layers may form localized heat-sources in the stack. The display layer with the high-shear modulus is a thermal transport layer through which the localized heat-sources-induced guided elastic waves propagate along an acoustic waveguide plane and can transport the heat generated by the light-emitting device away from the light-emitting device. Alternately, a display layer having a high refractive index may be sandwiched between two display layers having a low refractive index. The display layers with low shear modulus or low refractive index may be replaced with thermal transport layers having low shear modulus or low refractive index respectively.

摘要： In accordance with one exemplary embodiment the invention provides a multi-parameter fiber optic sensing system with an aperiodic sapphire fiber grating as sensing element for simultaneous temperature, strain, NOx, CO, O2 and H2 gas detection. The exemplary sensing system includes an aperiodic fiber grating with an alternative refractive index modulation for such multi-function sensing and determination. Fabrication of such quasiperiodic grating structures can be made with point-by-point UV laser inscribing, diamond saw micromachining, and phase mask-based coating and chemical etching methods. In the exemplary embodiment, simultaneous detections on multi-parameter can be distributed, but not limited, in gas/steam turbine exhaust, in combustion and compressor, and in coal fired boilers etc. Advantageously, the mapping of multiple parameters such as temperature, strain, and gas using sapphire aperiodic gratings improves control and optimization of such systems directed to improve efficiency and output and reduce emissions.
