Development of Interference Wedged Structures for Direct Registration and Quantitative Evaluation of Hg in Gas Discharge in Lamps and in Air

We develop simple and reliable technique, based on suitable Interference Wedged Structures (IWSs) as small-size, tile-like 5x2x0.1 cm device - IWS Analyzer (IWSA; Composed IWSA) for registration and quantitative evaluation of Hg (harmful pollutant) in gas discharge in lamps and in air. The main advantage of the IWSA technique is its applicability for direct observation with the naked eye of an illuminated IWSA through diffused or direct light from the object under study. We present theory, simulations, and appropriate realization for IWSA.
