Trace gas sensors are used in different fields. Light-induced thermoelastic spectroscopy (LITES) has extremely high sensitivity and offers non-contact measurement, attracting extensive research ...
The 3280A Series spectrum analyzers now come with a 30-MHz digital demodulator and generic vector demodulation as standard features with no price increase over its predecessor, the 3280 Series.
Current extrinsic fiber acoustic sensors face two primary challenges. The first lies in the time-varying initial phase of the interference signal, which arises from environmental vibrations, ...
