The newly developed Double Pendulum Interferometer (DPI) with its unique optical design provides the possibility of remote and in situ measurements of exhaust gases in smoke-stacks. The remote configuration is presented in fig. 1. Due to its design the DPI guarantees for - high short and long term stability - insensitivity to external vibration and temperature changes (Ref. 1). The instrument not only identifies the type of gas but also allows a quantitative measurement of gas concentrations (Ref. 2). Fig. 2 gives the computed emission for a high temperature smoke-stack (HF, H20, CO2, and 02) for an in situ configuration. Reg. 1. Jaacks, R.
