[Experimental research on optimization of QEPAS based spectrophone].
Guang pu xue yu guang pu fen xi = Guang pu, 2015The present paper studied the impact of geometry dimensions, located angle and detection position of a quartz tuning fork (QTF) on the sensitivity of QEPAS system. Ten kinds of QTFs were employed to compare the sensitivity with each other, and the results show that the QTF with a wedge-shape top obtains a higher quality factor and turns to be 50% more ...
