Abstract: A photo acoustic detection cell (6) is located within the optical cavity (3) of a cavity enhanced absorption spectroscopy apparatus (3,4,5). When a sample in the cell (6) absorbs radiation from a pulsed radiation beam coupled into the cavity (3) pressure waves are generated that are detected by a microphone (9). A detected signal (10) output by the microphone (9) may be processed to determine a value for the concentration of an absorber in the sample.

Abstract: The invention relates to a method for measuring the presence and/or the concentration of an analyte using a gas sensor assembly and to a corresponding gas sensor assembly. The gas sensor assembly comprises, in particular, a radiation-emitting radiation source (102), a gas measurement chamber (104) which may be filled with a test gas (110) containing the at least one analyte to be measured, and at least one detector device (108) which detects the radiation (116) and generates an output signal which is dependent on the presence and/or the concentration of the analyte. In order to meet increased safety requirements and to avoid the drawbacks of the known systems without inadmissible increased complexity and overall size, the radiation source emits radiation in the form of pulses and, during each radiation pulse, a large number of individual values (304) are recorded for generating an average measured value, the first of the large number of individual values being compared, during the first radiation pulse, with a predetermined threshold value and an alarm signal (136) being generated if the threshold value is exceeded.

A motor may be coupled to rotate and/or translate the object containing tube to present differing views of the object of interest. One or more detector arrays are located to receive the emerging radiation from the post specimen magnifying optic. Two- or three-dimensional images may be reconstructed from the magnified parallel projection data.
