New possibilities to increase sensitivity of the ultrasound non-linear modulation methods

Popis výsledku v původním jazyce

This paper presents comparison of two basic methods of ultrasonic non-linear modulation spectroscopy and proposes new possibilities for rising of sensitivity. The rising of sensitivity by lowering of a dynamic range of the measured signals by using of analogue linear pre-filtration for suppressing of excitation signals is discussed in the first part. The second part discusses the possibility of using the burst exciting mode for ultrasonic non-linear modulation methods. The excitation by phase coupled burst signals is derived for obtaining of the resultant long time signal without the waste of its useful energy. The new variant of mixing method with burst signals is derived, where the linear analogue pre-filtration is used for the attenuation of exciting signals in sensing signal for the rising of signal processing dynamic range and the increasing of practical sensitivity.
