摘要： A fluid analyzer (214) that analyzes a sample (12) includes an analyzer frame (236); a test cell assembly (242) that receives the sample (12); a laser assembly (238) that generates a laser beam (239A); a signal detector assembly (232); and a self-check assembly (230). The self-check assembly (230) includes (i) a check frame (230A); (ii) a check substance (230E) with known spectral characteristics; and (iii) a check frame mover (230B) that selectively moves the check frame (230A) between a self-check position (231B) and a test position (231A) relative to the analyzer frame (236). In the self-check position (231B), the laser beam (239A) is directed through the check substance (230E) to evaluate the performance of the fluid analyzer (214). In the test position (231A), the laser beam (239A) is directed through the sample (12) in the test cell assembly (242) to evaluate the sample (12).

摘要： An apparatus for quantitatively detecting isotopologue of carbon dioxide using dual-photon absorption, comprising a laser source, a laser frequency stabilizer, a sample chamber, a signal detector, and a signal analyzer. The sample chamber comprises an optical resonator and a piezoelectric ceramic. The laser source is configured to output a laser beam. The laser frequency stabilizer is configured to lock the laser beam to a mode frequency of the optical resonator. The piezoelectric ceramic is configured to adjust a length of the optical resonator to alter the mode frequency of the optical resonator to match energy levels of a target molecular isotopologue. The signal detector is configured to detect a transmission intensity of the light beam passing the optical resonator to obtain a dual-photon absorption signal. The signal analyzer is configured to analyze and process the dual-photon absorption signal to obtain a concentration of the target molecular isotopologue.

摘要： Imaging systems including an objective lens and a line generation module are described herein. The objective lens may focus a first light beam emitted by the line generation module and a second light beam emitted by the line generation module at a focal point external to a sample so as to adjust line width. Line width may be increased to lower overall power density of a light beam on a surface of the sample such that the power density of the light beam on the surface of the sample is below a photosaturation threshold of a dye on the sample.

摘要： The unmanned flying body is provided with a gas detector, a distance meter, and an altitude controller. The gas detector emits diagonally downward to the forward side in a moving direction of the unmanned flying body a detecting light frequency-modulated by a predetermined modulation frequency setting a predetermined frequency as a central frequency. The gas detector receives the light, returned from a measurement target to which the detecting light is emitted (an area on a pipe member for transferring gas, irradiated with the detecting light), as first light. The measurement target is checked for gas leakage based on the received first light. The distance meter measures the distance between the gas detector and the measurement target. The altitude controller controls the flight altitude of the unmanned flying body based on the measured distance.

摘要： The invention relates to an optical sensor which is used to measure at least one characteristic feature of a liquid and/or gaseous medium. By means of at least one light source, light is introduced into at least one optical guide (12, 21 to 24), which has at least one measurement surface. The optical sensor further has at least one light receiver. The optical guide (12, 21 to 24) is a ring resonator, into which light is outcoupled from a waveguide (11) and in which a mode profile corresponding to the outcoupled light component circulates, and the path radius and/or effective refractive index of which is changed by deposits (B) on the measurement surface. The transmission spectrum of the mode profile is determined by the light receiver. The ring resonator (12, 21 to 24) sits on a carrier (10), which is arranged on at least one temperature-setting element (27). The temperature of the ring resonator (12, 21 to 24) can be set by means of the at least one temperature-setting element. The evaluating device has the optical sensor, which is arranged in a measurement chamber for the medium to be measured, which measurement chamber is accommodated in a housing. The sensor is connected to the light source and to an evaluating unit, which feeds the evaluated signals to the temperature-setting element (27).
