Abstract: An instrument for determining the concentration of a particular gas that might be present in a sample has no moving parts and is extremely compact. The instrument uses as a source of radiation a device that has a radiating element whose temperature is alternated between T.sub.1 and T.sub.2 and whose spectrum approximates that of a blackbody. Radiation from this source is passed through a dual pass band filter that has two non-overlapping pass bands, one of which is centered at a wavelength at which the gas absorbs and the other of which is centered at a wavelength at which the sample does not absorb radiation. After passing through this filter, the radiation passes through the sample chamber and then is intercepted by a detector which produces an electrical signal determined by the radiation intercepted. The electrical signal is processed to provide an indication of the concentration of the gas.

Abstract: A radiation arrangement suitable for emitting IR radiation has a flat radiation source (2), the radiation emitted from which is deflected in at least one predetermined direction by a reflector (4); said reflector consists of a body, the circumference of which becomes smaller towards the beam outlet and the reflective surface of which is substantially surrounded by the radiation source; in an axisymmetrical arrangement, the distance between the radiation source and the axis of the reflected beam is greater than the radius of the reflector component arranged symmetrically in rotation along the optical axis. The radiation body may consist thereby of a resistive coating (2) on an electrically insulating substrate (3) or a self-supporting resistive strip or wire. An essential advantage here is that there is a relatively large area for the generation of IR radiation which can be bunched into a high-intensity beam by the reflector arrangement, as is necessary in measuring instruments, e.g. gas analysers.

Abstract: This invention relates to a method of and system for facilitating detection of a particular predetermined gas in a scene (14) under observation. The gas in the scene is typically associated with a gas leak in equipment. To this end, the system comprises an infrared camera arrangement (12); a strobing illuminator device (22) having a strobing frequency matched to a frame rate of the camera; and a processing arrangement (24). The processing arrangement is configured to store a prior frame obtained via the infrared camera arrangement; and compare a current frame with the stored prior frame and generate an output signal in response to said comparison. The system also comprises a display device (26) configured to display an output image based at least on the output signal generated by the processing arrangement so as to facilitate detection of the particular predetermined gas, in use.

Abstract: Thermally tunable optical sensors are used in sampling tools for analysis of samples from a wellbore. The thermally tunable optical sensors generate a series passbands of wavelength emissions and detect attenuation in a signal thereof. The attenuation detected is processed and used to determine aspects of the samples. Analysis may be completed remotely (outside of the wellbore), within the wellbore (during drilling or otherwise), or as a part of another process such as fluid management, transport and refinement.
