Abstract: An apparatus and method for analysing a gas of the kind adapted to produce an interference pattern displacements of which are indicative of changes of the constitution of the gas involves exposing an array 8 of photosensitive elements to the interference pattern. Respective digital indications of the intensity of the interference pattern falling of the elements are produced by means of a timing circuit 16 adapted to clock data out of the array 8 as a series of analogue pulses which are held by a fast peak detector 17 and converted by an analogue-to-digital converter 18 into digital indications. The position of a principal peak of the interference pattern is then determined by means of a microprocessor (not shown) adapted to determine the best fit of the digital indications with appropriate pre-stored values.
