摘要： Determining a temperature experienced by a region of a component comprising the steps of: providing a component with a temperature sensitive detection material in a first state and exhibiting a first chemical characteristic prior to its exposure to a thermal environment; exposing the component to a thermal environment such that the detection material is converted to a different state in which at least one region of the detection material exhibits at least one chemical characteristic different to the first chemical characteristic; identifying at least one region of the component in which the detection material exhibits the at least one chemical characteristic which is different to the first chemical characteristic; and determining the temperature experienced by the component in the or each region by relating the detection material chemical characteristic in the or each region to a temperature value by reference to a correlation of detection material chemical characteristic and temperature.

摘要： A method of sensing a process utilizing a sensing apparatus consisting of more than one diode laser having select lasing frequencies, a multiplexer optically coupled to the outputs of the diode lasers with the multiplexer being further optically coupled to a pitch side optical fiber. Multiplexed laser light is transmitted through the pitch side optical fiber to a pitch optic operatively associated with a process chamber which may be a combustion chamber or the boiler of a coal or gas fired power plant. The pitch optic is oriented to project multiplexed laser output through the process chamber. Also operatively oriented with the process chamber is a catch optic in optical communication with the pitch optic to receive the multiplexed laser output projected through the process chamber. The catch optic is optically coupled to an optical fiber which transmits the multiplexed laser output to a demultiplexer. The demultiplexer demultiplexes the laser light and optically couples the select lasing frequencies of light to a detector with the detector being sensitive to one of the select lasing frequencies.

摘要： A diode laser spectroscopy gas sensing apparatus having a diode laser with a select lasing frequency, a pitch optic coupled to the diode laser with the pitch optic being operatively associated with a process chamber and oriented to project laser light along a projection beam through the process chamber. This embodiment additionally includes a catch optic in optical communication with the pitch optic to receive the laser light projected through the process chamber and an optical fiber optically coupled to the catch optic. In addition, the catch optic is operatively associated with a catch side alignment mechanism which provides for the alignment of the catch optic with respect to the projection beam to increase a quantity of laser light received by the catch optic from the pitch optic and coupled to the optical fiber and a detector sensitive to the select lasing frequency optically coupled to the optical fiber. The catch side alignment mechanism may consist of means to tilt the catch optic along a first axis and a second axis orthogonal to the first axis with both the first and second axes being approximately orthogonal to the projection beam.

摘要： A pitch side optical system for use in diode laser spectroscopy consisting of more than one diode laser having select lasing frequencies with each diode laser being coupled to an end of a distinct input optical fiber. The pitch side optical system further consists of a multiplexer optically coupled to the other end of less than all of the input optical fibers with the multiplexer outputting multiplexed laser light to a pitch side optical fiber. The pitch side optical system further consists of a coupler optically coupled to the far end of the pitch side optical fiber and the far end of an unmultiplexed input optical fiber with the coupler combining the multiplexed laser light and the unmultiplexed laser light and outputting the combined light to a transmission optical fiber. Typically, the coupler is located near the combustion process. The pitch side optical system further consists of a pitch optic coupled to the transmission optical fiber. Typically, all optical fibers used in the pitch side optical system are single mode optical fibers.

摘要： An infrared spectrometer is adapted to capture spectral data at high frequency and includes an aperture defining slit and tuning fork chopper for periodically admitting infrared radiation. A lens and a plurality of mirrors direct the infrared radiation through pair of calcium fluoride prisms that split the infrared radiation into spectral components. The spectral components are directed by an additional mirror and lens to an array of lead selenide pixels that generate a set of data indicative of the spectral component intensities. Data collection circuitry coupled to the pixel array and coupled to the tuning fork chopper collects the set of data at a selectable rate at least once during each opening of the aperture. A serial output on the data collection circuitry provides a list of data values representative of the spectral intensity at each pixel which can be then stored in a mass storage device as well as immediately analyzed based on selected criteria.
