PROBLEM TO BE SOLVED: To measure a hot gas temperature in a gas turbine using a tunable diode laser.SOLUTION: A combustion gas measurement apparatus mounted in the gas turbine (10) includes: a tunable diode laser (22) emitting (110) a laser beam passing through a combustion gas path (30) in the gas turbine (10); a controller (20) for the tunable diode laser to be tuned (100 and 102) so as to emit a first laser beam having a wavelength of 1,334 nanometer (nm) and a second laser beam having a wavelength of 1,380 nm or 1,391 nm; and a laser sensor (22) sensing (100) each radiation beam passing through the combustion gas (30) and generating an absorption signal (112) indicative of an absorption of the beam by the combustion gas at each of the wavelength. The controller (20) executes a program which is stored on a non-transitory storage medium and determines (114) a combustion gas temperature based on a ratio of the adoption signals for the first laser beam and the second laser beam.
Abstract:
An arrangement adapted for a spectral analysis, having a light transmitting means, a delimited space in the form of a cavity serving as a measuring cell and defining an optical measuring distance, a light sensing means for detecting radiation passing said optical measuring distance from said light transmitting means, and a unit, connected at least to said light sensing means and performing the spectral analysis. Beams of radiation from the light transmitting means are made to pass through an optical band-pass filter at different angles of incidence. The filter is structured so as to pass a wavelength in dependence of the angle of incidence. A first chosen wavelength component is separated from a second wavelength component, each being received in its opto-electric means. Said unit is adapted for detecting and calculating an occurring radiation intensity for each such wavelength component.

Abstract:
PURPOSE:To make it possible to separate two wavelengths by one device, by using one common input slit for two diffraction gratings, which are independently rotated on the same axis, a collimator mirror, two telemeter mirrors corresponding to the two diffraction gratings, and two output slits. CONSTITUTION:Diffraction gratings G1 and G2 are independently rotated with a common axis X as a center. Light is inputted from an input slit S1. The light, which is inputted from the input slit S1, is made to be parallel flux by a collimator mirror M1. The light is inputted to the diffraction gratings G1 and G2. The light with one wavelength of the light inputted in the diffraction gratings G1 is reflected and diffracted and inputted to a telemeter mirror M2. The light is reflected by the M2, converged into an output slit S2, and inputted to a light detector PM1. The light with another wavelength of the light inputted to the diffraction grating G2 from the collimator mirror M1 is diffracted and inputted into a telemeter mirror M3. The light is reflected by the M3, converged into an output slit 3, and inputted to a light detector PM2.
