Abstract:

LOG-TO-DIGITAL CONVERTERS, DISPLAY SYSTEMS, REAL TIMELASER SPECTROSCOPY, AIR POLLUTION DETECTION, ATMOSPHERES, COMPOSITIONPROPERTYA high-speed system for making simultaneous wavelength-dependent transmission measurements on as many as four different wavelengths from a long-pulse solid-state laser has been developed. The new system can make simultaneous on and off reference absorption line measurements in absorption cell tests in a period of microseconds, thereby reducing effects of changes in cell optical conditions. An associated dual parameter analyzer contour mode display can present visual transmission data at any two chosen wavelengths for real-time observation purposes. A proposed system usage of in situ high-speed atmospheric transmission measurements is also presented in which reduction of turbulence effects can be expected, due to the imultaneous measurements. This will be of importance in measuring air pollutants where turbulence affects the concentration.
