    摘要： The present invention provides a method and a system for remote imaging of explosive gases in an area. The method comprises: illuminating the area with a light source having a uniform light intensity distribution over an infrared wavelength range; acquiring images of the illuminated area with an image sensor through gas detection filters having bandpass central wavelength corresponding to absorption curves of target gases respectively; determining existence of the target gases based on the acquired images; predicting distribution of gas concertation for existing target gases respectively by using a non-linear prediction model; and constructing gas distribution images of the area based on the predicted distribution of gas concertation. The present invention can recognize different gases with overlapping absorption curves and provide more accurate prediction of gas concentrations.

    摘要： A thermostatic module of a compact gas sensing device and a compact gas sensing device are disclosed. The thermostatic module includes a housing unit, a thermal insulation unit, a heat conducting unit, a temperature sensor, a heater and a control circuitry board. The thermal insulation unit is placed inside a first accommodation space provided by the housing unit, and forms therein a second accommodation space in which the heat conducting unit is placed. The interior of the heat conducting unit forms a third accommodation space where gas sensor modules can be housed, and also a gas passage channel. The heater generates and transfers heat to the heat conducting unit, whose interior temperature is constantly probed by the temperature sensor and input to the control circuitry board which dynamically adjusts the heating power by the heater to make sure the measured temperature is always stabilized around a preset target value.

    摘要： In an analysis device that irradiates light from three or more light sources onto a cell, embodiments proposed herein prevent a reduction in the intensity of light from each light source, and are provided with at least a first light source, a second light source, and a third light source, and an optical system that guides light from the respective light sources onto a cell. The optical system is provided with a second light source optical element that reflects the light from the first light source and transmits the light from the second light source, and a third light source optical element that reflects the light from the first light source that has been reflected by the second light source optical element and the light from the second light source that has been transmitted through the second light source optical element, and transmits the light from the third light source.

    摘要： The invention relates to a photometer (30) for analysing the composition of a sample gas. The photometer comprises an infra-red (IR) source (20) configured to direct a first plurality of pulses (40) of IR radiation through the sample gas to an IR detector (26), at least two of the first plurality of pulses being of different wavelength. The photometer further comprises an ultraviolet (UV) source (32) configured to generate a second plurality of pulses (38) of UV radiation for conveyance to a UV detector (36), at least two of the second plurality of pulses being of different wavelength. A path selection arrangement (22, 42-50) is configured to selectively convey different ones of the second plurality of pulses (38) to one of the sample gas and the UV detector (36). The photometer further comprises processing circuitry coupled to the IR source (20), the UV source (32), the IR detector (26), the UV detector (36) and the path selection arrangement (22, 42-50). The processing circuitry is configured to (i) select the wavelength to be used for a given UV pulse of the second plurality of pulses (38), (ii) receive a plurality of detection signals from each of the IR detector (26) and the UV detector (36) and (iii) based on the detection signals, determine a concentration of at least one component of the sample gas. A method for analysing the composition of a sample gas is also disclosed.

    摘要： A concentration measurement method performed in a concentration measurement device including an electric unit having a light source and a photodetector, a fluid unit having a measurement cell through which a gas flows, and a processing circuit for calculating a concentration of the gas based on an intensity of a light passing through the measurement cell. The concentration measurement method includes a step of determining an absorption coefficient of the measurement gas using a reference absorption coefficient determined in association with the reference gas and a correction factor associated with the measurement gas, and a step of obtaining a concentration of the measurement gas flowing in the measurement cell using the absorption coefficient of the measurement gas. When the absorption peak wavelength of the measurement gas is longer than the peak wavelength of the light source, a reference gas having a longer absorption peak wavelength than the peak wavelength of the light source is used, and when the absorption peak wavelength of the measurement gas is shorter than the peak wavelength of the light source, a reference gas having a shorter absorption peak wavelength than the peak wavelength of the light source is used.
