Paper Abstract

A far infrared Michelson interferometer which includes a laser fringe sampling channel and a hydraulicpiston to move one of the mirrors linearly has been developed. A maximum resolution of 0.08 cm-1 can be obtainedwith the present length of the piston. The buffered analogue-to-digital converter unit allows the interferogrampoints to be transferred in blocks to a storage device while the mirror is travelling. The instrument has been usedto detect weak absorption bands due to water vapour believed to be either adsorbed onto or trapped in the filmof chemically modified epoxidised natural rubber.
