| Description
| - Byla studována spektra molekul (CH4, NH3, N2O a ethan), které jsou součástí atmosférického znečištění způsobeného emisemi automobilového provozu. Testovali jsme metodu fotoakustické detekce společně s polovodičovými lasery jako jednu z možností sledování nízkých koncentrací těchto atmosférických polutantů. Byla získána závislost intenzity fotoakustického signálu (PA) signálu na tlaku a při nejlepší odezvě (optimální tlak) byla stanovena mez detekce jednotlivých plynů ve směsi se vzduchem. Za stejných podmínek ( tlak plynné směsi, fáze lock-in zesilovače) byla kvalitativně a kvantitativně proměřena spektra automobilových výfukových zplodin pro různé teploty motoru. Zdrojem záření byl nový typ polovodičového GaInAsSb/AlGaAsSb laseru pracující v oblasti 4342 – 4362 cm-1 za pokojové a vyšší teploty. (cs)
- A study of the infrared spectra of the CH4, NH3, N2O and ethane gases carried out. These molecules are part of atmospheric pollution caused by emissions from automobile traffic. We tested the method of photoacoustic (PA) detection together with the laser semiconductor emission as a new tool for monitoring of limited concentrations of these atmospheric pollutants. The variation of the intensity of the PA signal with pressure was studied. The detection limits were determined for the individual gases in mixtures with air at the optimum pressure. The spectra of automobile exhaust gases at various motor temperatures were measured qualitatively and quantitatively. A new type of semiconductor GaInAsSb/AlGaAsSb laser, working in the 4342 - 4362 cm-1 region at room and higher temperatures, was used as the tunable radiation source.
